[QUOTE="BWH2003, post: 9621719, member: 32209"] Yeah I hear you there. Actually Rick at Amazon Tuning is the tuner for the car and I can say he has been more than helpful throughout the process. The reason I posted was to see what ideas others had about the issue. I think we are both dumbfounded as to what is happening with the car. I reflashed the last tune Rick gave me. It was fine two weeks ago with the same tune and now its lean. It seems every sensor is good and thats why im lost. While using the diagnostics on the predator the short term fuel trends are at +25% which I guess is the max it can pull out of the car. So it is definitely super lean which is what the wideband is indicating. The only thing left is something to do with fuel delivery but it holds 39 psi and really doesnt change. The odd part about all this is at full throttle the afr is good. Its just everywhere else the car hesitates and goes really lean. [/QUOTE]
