i got an 1jz gte swapped sc300, sometimes it pulls hard around the 3000rpm range and sometimes it doesnt really pull at all. is it a turbo problem? how can i figure it out?

do you have a boost gauge? is it holding boost steady, or bleeding off? Any popping or backfires? Smoke?

boost leaks?

ehh no boost gauge completely stock except for fmic n bov, itll hold the boost steady at higher rpms like 4800 n up but when its at the 3000 range it doesnt do that initial pull and sometimes it doesnt sound right either. theres no popping or backfires and there is some white smoke sometimesbut not enough i think for a blown turbo.

Get a boost gauge cause thats the only way your going to tell if its holding boost properly.

"seat of the pants" boost gauges don't work, get a real one.

Perhaps your BOV is stuck open sometime? it's a pretty common problem.
