Hey guys, i have R33 gtst 95 model, rb25det engine, anyway car is basicly stock turbo, stock computer, has 3" turbo back exhuast, greddy fmic, avcr b/c, split fire coilpacks, walbro 255L fuel pump installed, now if im travelling along at 60km/h drop it back to 3rd or 2nd and flatten it, goes through the rev range fine until it gets to 5000rpm then it feels like it drops off power until about 6000 rpm then comes on full power again until redline at 7200rpm, now i dont know much about the avcr i have it set up on self learn mode, i have been told that its not the best way to run it, but i just got it set up so it goes to all stars and left it so it was safe, running 10psi which is about right with what a standard car would run with ungraded exhaust on it. still does has this problem at that boost. any ideas??
Cheers
Daz
