The injectors, chip and FPR need to match. Are they? Or did you piece the system together? We had a Promotive system on a 3.2 and it worked just fine with stock and 52 lb injectors (with the right program).

The whole thing has to be designed/programmed to work together, incl boost pressure.

Is the FPR plumbed correctly? Are you boosting your brake booster?
The entire system has been in this configuration for 5+ years. Yes, I am boosting the brake booster but I have already choked off the hose and saw no difference.

Gasoline is fresh - 93 octane normally from Chevron.
