I would like to know if it is ok to use Toluene as an octane booster. Any coments or experience? thanks

what would be the advantage of replacing these? can you (or someone else) please explain what would be the benefit of doing this? thanks

I am trying to find out what brand and part number are the turbo on the Cayenne TT. I am trying to upgrade them, but my tuner has to have this info so he can tell me what he can do for me thanks :drive:

let's say for a minute that i want more power or "better mpg", if i added an octane buster each time i fuel my car would that cause damage to the engine? does anyone know/have any experience with them? thanks

what are can someone do...if it gets too hot; drive away from the kitchen :drive:

darn... i had not problems with them. robert or Mike Cooper are the people to talk to. so far no oil consumption... but MPG is down to 12.2 from 15.9

thanks Loren

CTs, i went to the dealer to get a Cayenne TTs the week before I installed the DMS upgrade becasue of the leftover lag on my tt 9ff, and according to the dealer the TTs is a TT with the powerkit and better ecu mappings. I am not trying to say that the TTS is not a good buy, but i will need something a lot better than what i have (with either the 9ff or DMS software upgrade) for me to get a new cayenne. When i called 9ff to check if their turbos for the cayenne were upto par with the ones on the TTs i was told that they are the same as the ones on the TT. i will ask the dealer about installing the TTs turbos on mine to see what they say :D this is the way to find out....at least for me. I let you know next week about what the dealer has to say about the turbos. Phil's email address is Philydms@aol.com (the official email is Pyoung@dmsautomotive.us i believe)

I have done the dyno thing as I do with most of my "upgrades". With the Fabspeed I lost 12.35Hp and 15.26 lb-ft. I do not do air filters because they are more likely to cause engine damage. I have tried, as I said before, TechArt, Ruf, Gemballa, 9ff and DMS. With DMS I am at 536.31 HP and 543.2lb-ft boost was a bit higher than .9 bars (when I say a bit higher than .9 bars is more than .9 but less than 1, no lag at all. With 9ff I was at around 515 Hp and 520lb-ft boost at a little better than .8 bars and about 80% of the lag fixed TechArt, Ruf, Gemballa were all around 505-510 hp 507-512 lb-ft. with not much of a hit on MPG, 1-3 less miles per gallon, and a bit less than 70% of the lag. With DMS I am taking a bigger hit 2-4 less miles per gallon than stock, and I can not comment on the oil consumption yet because I have only 300+mi with this new software. I ride this car as my 911t, and my dealer has seen the engine on the 3/4th temp range for about 20-30 minute run with me driving ;) and then with the dealer’s main engineer. They called Porsche and the only fix was to get the bigger intercoolers if I was going to ride the Cayenne as I did with them. So I have changed my intercoolers for the ones on the Powerkit and that has helped quite a bit on the engine temp. I want to make sure that you understand that I have no relationship with any vendor besides the fact that they take my $ and I get their product. I do not get any kickbacks, or special deals. All the vendors or tuners delivered what they promised with the one exception, but as Loren said that does not mean that the rest of his products are bad. I will be upgrading my 911t with 9ff this summer or early fall, I am going back home in July and their factory is not very far from my parents; and next week i am upgrading the breaks on the Cayenne (both fron and rear) i hope it helps

Porsche Nuts, call the people at DMS, they will tell you the FACTS. They do not need or will make up stories. Robert, the man behind DMS, is a straight shooter. Phil the Rep here in the USA is just like Robert. If you buy a Cayenne and it does have an e-throttle issue (call it lag, call it hesitation or whatever) I bet these guys could get your S or V6 to run a lot better than the OEM. If I had gotten 1/2 of what they delivered to my TT I would have been really happy. As for Fabspeed I tend to believe that if you fail to state the truth like they do “+27.6HP Twin Turbo. Better than any German European systems 100% guaranteed.” I would not trust them on anything. As a matter of fact, I will call them and ask them for my $$ back since they are 100% guaranteed. I let you know tomorrow what there is to say about their word. Mudman2, what makes you think that after insulting me or trying to take a cheap shot at me, I would give you anything…. Please do yourself a favor, stop thinking that the rest of the world is as stupid as you think we are… I have yet to read anything constructive from you, unless of course when you beat your own drum.

Porsche Nut, mine is a Cayenne 2005 TT, I have tested TechArt, Ruf, Gemballa, 9ff, and DMS and DMS is quite a bit better than the software from 9ff, and light years from Ruf, TechArt, and Gemballa; Ruf, being the worst of all of them. I am not saying that these other vendors are not good, but this is just a comparison among all of them. With DMS my gas mileage has gone to 13.4 MPG and the lag on the e-throttle is COMPLETELY gone. No more hesitation, no more delay in hard left corners, the Cayenne now is like my 911t, just a monster! As for mudman2’s comments I do not know him, so I can not comment on his knowledge, or lack off if. I speak facts that I have EXPERIENCED, and I have nothing to gain from ANY of these vendors unlike other people. The only one thing I am sure is that dynos in good hands do not lie, and when I put the Fabspeed bypass on my Cayenne 05 TT I lost 12 hp and a little less than 15 = r x F = r F sin( oo). Both hp and delivery were a lot sharper than stock, and that is why I took them off my car. If someone pays for shipping I am willing to give the fabspeed away, but be aware that they do not improve the engine’s performance.

I agree, Fabspeed = no good i lost about 12HP on the dyno (05TT) do you want more power and torque, get DMS to program your ECU, then you will never sell your car :)

I want to upgrade the front and rear breaks on my Cayenne turbo. specifically i want to get the powerkit front breaks on the front and move the cireent ones to the rear. can you, do you know of the parts that are needed to do the upgrade? I am upgrading the intercoolers this comming week :)

thanks. the link does not work.

Loren, I am trying to get the complete part list for the powerkit upgrade for the breaks and intercoolers. will you give these for "free" or i need to contribute? thanks peanuts

hae you tried this in your Cayenne?

DMS is a small tunner from England. http://www.dmsautomotive.com/index.asp?upid=18&msid=3 I asked arround, and did not get people to answer but those who did were very happy customers. As i said before i have tried many of the most recognized tunners but i have not been happy at all. specially with ruf, almost $18k for nothing but arrogant service from them. these guys at DMS are something else, I called England and talked to Robert, and he sounded like an honest man, then I called on the rep here in the USA (Phil) and he was also very straght and nice. he had some few other customers on the west coast so he flew to in and we did the upgrade here. I do not know what Robert can do for your V6 but you loose nothing by calling Phil and asking (1 630 936 2767). I know of other people in these forums that do get kickbacks from their reviews, I do not and will nerver ask for a discount from these guys they JUST delivered more than what I was expecting. the one thing I was just made aware from an older customer is that the fuel consumption goes up about (10%) as it does the oil. but we will see. In the meantime PORSCHE will have to come up with something MUCH better than the TT S. You would have to pay me for the DMS upgrade for me to get one when Robert has one :clapping: I HAVE NOTHING TO DO OR GAIN WITH THESE GUYS. I am just a happy client.

I want to replace my front disks with the power kit's. I just upgraded my ecu with DMS software and better breaking would be a big plus. Also can I move the current front disk assembly to the back? Thanks

:jump: After installing the DMS software in my ECU the Lag is GONE! I test drove the TT-S this past Wednesday, and I am driving a far superior car today! It is not that I can not afford to buy one TT-S, I just do not see the need anymore. Granted that I just had my car back for a couple of hours, and I do not know how the fuel consumption did if any get affected, but man I almost hit the car in front on the first red light. It is a real eye opener! how easy I got used to the “LAG”. It is not just the lag, it is everything else between 1700-2000rpm and up. Why is it that Porsche did not do this from the very beginning? Why make its customers put up with substandard and dangerous engine mappings? I have seen the light, and I never go back to any other company to “fix” my car, techart, ruf, gemballa I tested them all. They all got the chance to do it right and did not. The closest thing would be 9ff but then why settle for them when you have DMS. Again I have no bias but the product itself. I have spent at least well over $10k trying them all. Thanks Phil and Robert I just hope that the car is as good as today in the heat ;)
