I think I did pushed it a little to hard too.... I have it dialed down now a bit to just barely see 1.30 bar and hold it all the way through the gears on 100 octane..

My pump mode is dialed in perfectly!

Email me, and I will shoot you over the Dyno Sheets

Again, Thanks for ALL the help over the phone, PM and ect.... I have learned a TON in the last 48 hours... Keep the inof coming! Thanks Mark!

Thanks Mark!

Usually when the MAF goes or is gone, you will run rich as a failsafe.

thast exactly correct.... thats why I know its the plugs.. plus Dave pushed the car past 1.3 bars I think... and the plugs should be changed in my opinion every 5K when ur running 1.3 bars on big turbos...
here is what u need :
Denso Double platinum 3245 PK20PR-P8 .032" (0.8mm) $7.16 for the
plug

When the plugs hesitated under boost PSM/ABS would come on before realizing/changing them out, CEL never came on, which is why i also think its plugs!

Goodluck

It couldn't be MAF, most likely it's the plugs.

[quote=RennTechV12]I've blown several MAFs while in the testing phase; both in my TT and the GT2, and the car ran fine. I got a small hesitation and lifting of power when the actual MAF blew, then the car ran fine.

I had the same result!

Alright, so the final outcome was - MAF I took it down to Todd at EVOMS and he gratiously got me in right away and hooked the computer up and it was a blown MAF....

I had a new one installed and the fault codes went away!
