Hello everyone.
I am fairly new to this board and this is the first question I have had to ask.
I have read quite a few posts and am impressed with the knowledge some of you guys have.
My big question: I have a 92 turbo supra- (automatic with basic upgrades,
HKS intercooler with hard pipes, 3 in exhaust, greddy profec boost controller, upgraded turbo, etc). Until recently the car ran perfectly. Now I hit fuel cut when ever I accelerate hard. With the boost controller off I should be running stock boost limits and not hitting FCO. I have checked for leaks, found none. I checked timing per documentation, it is set to 10 degrees with e1/t1 jumpered. Unjumpered timing goes to about 5 degrees. Is this the issue? or could it possibly be a stuck wastgate? The car run good as long as I drive without boosting past stock limits. Problem is like having boost controller set on and being set to high.
Any help is appreciated...TIA
