Well today i decided to install my new walbro 255 pump. I got it all installed fine and i went for a drive. The car stays rich but hesitates like crazy. I mean the whole car like shakes and then the power starts to hit. It only does it when i hold the throttle at wot, when i hold it a little and let boost and revs build up slower it rarely does it. if i am in like 3rd and hold it after all the major hesitations go away there are still minor ones. I adjusted my FPR to a low psi of pressure but no change. During the install i did everything to spec. The only thing i did different was the wires i connected straight to pump assebly where the stock ones were. I cant think of anything. I looked for vacuum leaks and even regapped my plugs down to 32. But still no change. If you guys can help me out that would be great. Any suggestions are greatly appriciated.
