Hey, wondering if anyone’s car w/SR20det has done this: pulls hard all the way to redline if you’re say cruising in 2nd, and step on it. if i am in 1st gear WOT, right when i shift to 2nd and hit the gas it gives me 0 power and wont accelerate for a second, then BAM accelerates hard again. the weird thing is, i watch the boost gauge, and its spooling up, but no acceleration for a second or so. very weird. 99.9% sure its not a vacuum/boost leak. feels fuel delivery related. ---

The stock bypass valves are notorious for leaking. Mine leaks like a dirty sluts ass. ---

as far as i can tell, there are no more boost leaks, and the re-circ is infact re-circing. i replaced the fuel filter with a z32 filter, and fuel pump is now a walbro 190… i can’t figure out why its hesitating right after each shift… how much can the stock MAF flow on the t25? i can’ t figure this out… (BTW the new fuel pump cut the hesitation in half) i want to figure this out before SCC or else there is no point in me competing. ---

that same problem has happened to me once or twice now. its only ever done it right after im done washing my car and i step on the gas as soon as i leave the wash bay. no idea if these two things are related…seems like it though. ---

the harness to the maf is tight, but i noticed there is a hole in the rubber boot covering the wires… hmmm
