Just finished installing my heads, intake, injectors, and afpr. The car is sluggish and jerky until about 2800rpm, then it kicks in suddenly and throws you back in the seat, pulls like crazy way up past 6k. I think I'm leaning out at the bottom of the rpm range. I tried bumping the fp up to 50psi.. it got better for a while and then went back to doing it after a few minutes.
See my sig for details (more in my garage), the injectors are bosch 4-way 19#'s. Just out of curiosity I hooked up my old pro-m 75mm bullet and mac cai - it doesn't do it as badly with that setup, but it still hesitates at the bottom of the gears.
Anyone have any suggestions? Am I looking in the wrong place with the fuel pressure, could it be something else? I have 2 new bosch o2 sensors, tps is set properly, new iac and ect sensors.. can't think of anything else. Could a vacuum leak be causing this?
