This is my first time posting a log, I hope it reads right. This is of the problem my car is having. The problem is when I get into the gas from either a slow roll or a stop. The car will "bog" or "stumble" when boost comes on to about 5psi then it clears up and pulls very hard from 5+psi up to redline. The car will also
do this when rev'ing it in the driveway. Hit the gas hard and it goes flat and then clears up at the top of the rev, audible knock is very clear when doing this. It seems to be very lean when getting into the boost causing the bog, this is what it feels like, but when the fuel is catching up(being added) to the boost/revs the car comes back to life. I have no way to interpret what I see in these logs. This is basically my first time messing with this stuff. On a side note if I have the car in 3rd and hold the revs to about 3600rpm for about 3 seconds the car will accelerate under boost without this bog.
Ed Wright did this tune and I sent him these logs but haven't heard back from him yet, I would like to drive my car but the way its acting I don't want to ruin this new engine. I know the PCM has to go back for a retune but can anyone tell just how bad it is or what is happening from what I posted? I can email the full log if needed, I deleted the time stamp to clear up the log.
Thanks,
Jeremy

Yep, looks like you really need more fuel.

I would be really carefull with the 10+ retard readings you are getting. Take it easy..... It's hard to tell when in enrichment without throttle pos. O2's look pretty lean. IAt's look good. my .02

Thanks Buddy Was kinda figuring she was going lean. When idling she is very rich, and stinks everything up, so this whole tune is a lil wacko. I thought I had throttle pos logged too but found out I didn't when I was opening the logs up in excel. I am not driving it right now because of the way it is running I don't want to toast this new engine that would just suck lol.
Thanks on the skull, it was airbrushed on by my girlfriends brother, he did an excellent job. I need something done to that ugly ATI plenum

I would say lean also. My car would do the same thing when it was super lean as verified on a in car wideband. You really should get edit and in-car wideband. It makes life so much simplier.
