Tuning Help Needed.....

Kmiller86 · 07-29-2006, 08:49 PM

Ever since I got my stroker broke in I have been having problems at WOT. It seems that almost everytimg I come close to 6k rpm, the car will sputter. The log shows it spike lean. I have tried to add fuel to no affect. I also adjusted the airflow adjustments on dsmlink with no affect. I have no idea what to do next to try to get rid of it.

Thanks
Kyle

Kind of an idiot check, but is your vacuum line plugged into your fuel pressure regulator? I made the terrifying mistake of doing this once and had the same symptoms.

.... Yeah that is one of the first things that I checked (boost leak test) with no leaks

Actually, the fuel pressure solenoid would prevent this problem from evidencing itself during a boost leak test. But good to know that's not it.
