Message So while im waiting for more funding for my TT motor build, I thought i would have some fun with my na and hook up my winfactory 1000cc top feed and also my dual intake with the selin translator. At Idle I adjusted the injectors to produce a 14.3 afr and at wot it sits between 12 and 13. now im sitting at idle and just smash the pedal to the floor ( instead of a nice easy roll ) the car imediatly hits 10 afr and sputters and chokes on all the fuel for a few moments until it can clear it and resumes normal behavioral acceleration. Is there something i need to modify in NIStune to keep this from happening? could this just be due to a rediculous setup in an NA?

Another issue I noticed is occasionally I will get a lean condition at idle if the AC is on. I have no idea how those correlate...

Finally, has anyone experienced an intermittant drop in fuel pressure (say droping 8 psi randomly...holding there for 20minutes or so, then resuming normal psi) while using a Aeromotive FPR?

Thanks for your help or comments on all/any of these, oh and yes my mod list is up to date


TT BEAST IN PROGRESS!
