someone else on here said it takes awhile for the ecu to reset so i am hoping that they are correct and everything will be fixed soon.

I won't disagree w. them, because there is a slight bit to gain as the ECU modifies the short-term and long-term fuel trim with time. But, for this mod it should be significant enough off the bat before any ECU adaptation occurs. That is exactly how it is for me everytime I had to do a full reset (for whatever the reason). Do you have a MT or AT? It may be less perceptable w. an AT ... no thanks to the torque converter.

Re: Installed Crawford Plenum and Lost Power

i finally got the info i needed, i talked to doug at crawford. he said that the program i had my ecu flashed with was the old one designed around the 6 speed manuel, since that program the realized the the 5 speed auto ecu's are much different and when you install the plenum it retards the motor in 3rd and 4rth gear. so he gave me the new reflash number, and i sent the ecu back to technosquare yesterday. and ill keep people posted if the reflash fixes the problem.
