okay guys, i got this problem thats bugging the crap out of me.
list:
Sr20 red top
t25
fmic and piping
walbro 255
greddy bov
stock fpr
stock exhaust
on cold start, it turns on perfectly, idles fine, PERFECT. i always let my engine warm up so when i start driving, i usually never go over 3k rpm but when i get onto the fwy i gun it and at about 3-4k rpm its starts to bog all the way to 7k+ rpm, i drive it at about 50% throttle and i can just feel it hesitate like it has no power but if i ease off maybe like to 10% throttle it feels fine. sometimes at idle it just wants to die goes all the way down to like 20, literally 20 rpms and it just turns back on.
checked maf, plugs, boost leaks, etc. and even got 300zx fuel filter
let me remind you that it was running perfect until i changed the clutch then like a day later is started doing this
***also, when i go to a gas station to fill up, i open up the gas tank and i hear no air swooshing and im also getting like 150 miles to a tank of gas :(
