KA24DE-T Breaking up under boost?
Ok so i had a small issue a few weeks ago where I was getting weird break up issues under boost. It was usually only under high boost (13-15lbs) and when it would break up my car would go very rich (10.1 on wideband). I changed the plugs, cap and rotor and the issue went away immediately. Infact the car felt better than before the break up issues. Anyway...a few weeks pass after I did the small tune up and went to a drift event where the car ran great until the end and I started getting small break up issues once again. The car still made power but decided to call it a day once the issue came back.
Anyone have any info why it is doing this? I have a feeling it's a fuel issue considering it goes super rich. I decided to change the plugs again (BKR7e) today just because, I checked for leaky injectors...they're all good. Fuel pump works just fine, FPR is reading 40 psi at idle and I'm assuming is good while driving also. I'll leave it at that for now. If anyone can help me out I'd greatly appreciate it. Any other info you guys need just ask and I'll post up what else you might need to know about the car...it's a built KA-t, .60 a/r, walbro 255, 760cc injectors, aeromotive fpr etc..
