car is bogging after replacing ECU
About a month ago I swapped my Skunk2 ECU (that came with the car when I bought it) with a stock P72 ECU I bought off Ebay. Since then, the car doesn't run as rich as it had been. No more two-tone back bumper. However, I have noticed a big decrease in performance and the car seems almost bogged down at times. When I am on the highway, the car really drags in 4th and 5th now especially. It's like I can have the car floored in 5th or going from 4th to 5th, and it is really reluctant to rev past 4500 (vtec engagement). The car tops at like 90 mph now. What's the deal? With the other ECU, while the car didn't seem to run more efficiently, it definitely seemed quicker. I'd like to run my car at the track this year but the way things are going it isn't looking good...
