Dumb Ole Donkey

It's really not just about enhancing low end power/torque. It's a known problem with the deadspots that you and I both have and their fix to them. As far as I know, these are the iterations of Evo HF Intake and the solutions: 1) oversize pipe reduced air velocity and screwed up MAF readings. The fix was to change diameter to the same as stock 2) one piece design which doesn't use any of the stock piping. They thought the resonance chamber just reduced sound or reduced efficiency and they still sell another lower cost kit to bypass it. But they then discovered that Porsche does somethings for good reasons and this was their lack of understanding. The fix was to cut down the Evo piping so that the entire kit uses some of their piping and some OEM. 3) This is version 3 and the end result is no dead spots All 3 runs Monday night were with the same program. The ECU just had some extra adaptation to do. It's the canned standard program by GIAC designed for the new new new Evo HF intake. Unfortunately, there still aren't any Evo HFs to buy right now as production is horribly behind. :( If I were you, I'd wait and try the new intake. Or if you want, wait for me to get mine and report back. If it doesn't work, I'll be pulling my hair out but if it does, I'll be super happy. I'm bound to be the guinea pig so you might as well wait. I can assure you almost definitely that your power dips are not AFR related. I have a huge dip at 6k but I'm just over 12.0 AFR right there. What this means is that we're not messing up our cars. We're just annoyed.

Then I consider myself lucky. Although the person wasn't exactly helpful, he at least was quite forthcoming in offering me a refund :) And it was about 3 weeks after I got my DME back before I managed to contact him. They really should give you money back. It says "Satisfaction Guaranteed" on their website. I'm sending mine back next week when I'm travelling to minmise inconvenience. <{POST_SNAPBACK}> Okay, I got my car dyno'd last night. Three runs. The first one was just as bad as with the Scargo Intake/custom program. The 2nd one was no better but a bit more power. The 3rd one had a perfect AFR but not as much power as the 2nd run. The computer was finally able to adapt my car into the proper range. This shows that everything is working okay together. The power results were disappointing as I lost 7hp from the Scargo/custom program. I'm still up over stock and that's with an open exhaust which surely costs me a hp or 3. The power dips I'm feeling are caused by an air resonance problem. The car is not leaning out and I suspect that yours is not either. The latest and greatest EVO intake uses an OEM section of tubing because the stock part has some sort of butterfly on the inside to stir the airflow just so. I waited for 2 months and EVO still can't supply me with one of these new pieces so I installed the previous model. My program is working well enough and I'm probably not hurting my car but I do want the improvements of the "fixed" intake so as soon as they will give me one, I'm switching over to that.

I can't get a refund on the GIAC. I let them talk me into driving "a bit" lean at first. Then, it took about 25 days to develop problems. It was day 31 before I could get the installer to return my calls and try to help me. I finally got fed up and started talking refund and they refused. The offer was to buy a new Evo intake or wait 2 months with my car getting worse and worse only to have them put it back on the dyno and use it as a test mule even further hoping to get it right. So, tonight I'll know 2 things. Am I lean anymore? How much power am I making? If I'm lean, I'll keep pushing and can possibly get a refund then because it's no longer a custom program issue. I'll be happy enough as long as it's not lean though. I wish I had started with Revo instead and if I do end up getting a refund, that's what I'll try next.

I did that exact upgrade on my previous Boxster S. I kept the original muffler for when I sold the car but ended up trading it in as is. I still have a good original Boxster S muffler which has sat in storage for a couple of years now. I wouldn't mind selling it if you are interested in buying it. On the other hand, I did like the sound of the hollowed out muffler so if you want to go that route, I understand. It is res'y though and you won't spend much time under 3200 if you do it.

Don't waste any more money or time on the GIAC program. I've been through quite an ordeal with mine. I started with the scargo intake. GIAC's program is specifically written for the Evo Highflow Intake. I called first to make my GIAC appointment at Dynospot Racing and they said the scargo would be fine. I had the scargo installed and drove straight to DSR for the flash. After doing a baseline, they found that I was very very lean (like 15.0). The guy there warned me that I was probably too far off for the program to fix my car. He then tried and he was right, not even close. The diameter of the scargo pipe is too big throwing off the MAF readings. He then suggested that he could have Garret write a custom program for me for an extra $200. Garret worked on it for 3 hours coming up with several different programs. In the end, my car was dyno'd 9 times. The 9th dyno showed me under 14 for most of the rev range, but never lower than 13.5 and mostly 13.8 and 13.9. They sent me home telling me everything would be fine. A month later, my car started to run funny. I developed a bunch of dead spots and even some backfiring. I was told I could either deal with it for 2 months until Garret could try and rewrite a new custom program for me or just take out the scargo and install the Evo. I ended up taking out the scargo and installing the Evo. I got reflashed with the regular Evo/Boxster program and since then, the car is running normally and stable but it has a huge dead spot at 4200. If I lift at 4200ish, it's like I slammed on the brakes. Sidenote: with the scargo, it was like that through the whole rev range. Very hard to drive when you can't lift. Anyway, I have a dyno appointment this Monday. I suspect I am probably leaning out in places and if so, I don't know what I'll do. It's frustrating and I would never recommend GIAC to anyone. If you can get a refund, do it. It's unlikely to ever get better. And at least with the Revo, you can get flashed and drive around before you pay a dime. If it has goofy deadspots or other problems, you don't even have to argue with anyone. The program expires in 5 hours. If you like it, then you pay to have it permanently installed. I'll let you know how my dyno goes. But note, I'm having some issues and I'm using the canned Evo package which is supposed to be perfect.

Thanks but I was at the dealer this morning for something else and the mechanic showed me what to do. Unfortunately the glovebox has to come off so I might do it myself but I might wait until I can drop it off. Just in case it wasn't clear, this cover is obviously not right. What has happened is that the airbag cover on the inside corner is sticking out very loose. They said they could do it for me but apparently forgot when they had it. They said they could take care of it the next time I dropped it off.

My airbag cover has come loose on the lower left corner. The dealer said it was easy to adjust but when I dropped it off they either forgot to take care of it or came back. I'd like to save myself a trip to the dealer and would prefer to just adjust it myself. I have no idea how to do it, though. Thanks.
