ECU Reflash EVOM or DMS

[virkdoc]

Hi

Im planning to get a ECU flash om my base Cayenne 2006, 3.2L V6.

I have spoken to EVOm and DMS. What is the opinion of the forum? Which would be better or more reliable? I know a lot of people are running these flashed ECUs...what is your experience with them or a reflash in general.

Also I want the sound more throatier...will a cat bypass fabspeed pipe help?

Thankssss

IMHO a waste of money on a normally aspirated engine. 10 - 15 HP at best (regardless of what the salesman told you).

If you really want more power trade for Cayenne S or a Cayenne Turbo.

Some tuners flashing can produce huge HP gains on turbo engines with the proper exhaust and diverter valves - but do very little on normally aspirated engines.

I would tend to agree with Loren on this. Sometimes you can get a little better throttle response and a little more BHP & TQ but not much. I use Eurocharged in my CTTS and my Audi RS6 (Both Twin Turbos) and for the 3.2lt they claim 14bhp & 14lb/ft TQ but in reality it is probably a little less than this.

also one of the salesman said to get a dry weave filter instead of an oil based filter??

Whats the opinion on the fabspeed sec cat bypass pipe?

You can do a bit of searching on the filter but I think there is a bit of concensus on the the internet that with Hot wire Mass flow sensors that you should stay away from any oiled filter. Stock filters are fine but many, and I would also tend to agree say that the oil soaked filters will cause the MAF an early demise. Think of a frying pan that you have burned oil in, once it is burnt you can clean it but you will never get that black burnt film off it again. Every time a MAF hotwire starts up it super heats to burn off contaminants and if there is oil on it....

I have the Fabspeed and they are overpriced but I paid it. My CTTS sounds better but only slightly louder and not really noticeable at cruise. Power increase is probably only half of what these companies claim.

I agree with the others, any gain from a tune on a non-turbo would be minimal. If you are looking for sound then just do the e xhaust.I have Fabspeed sec cat bypass, makes my ctt a touch louder and not really noticable at all on highway...however I think on non-turbo the sec bypass would probably be louder since the turbos will not be there to quiet it down from the get go.

Read up on oil filters....it says that the oil on the filter is so minimal like 1.5 ounces that its impossible for it to fly off.....
