:ugh: ok i fixed one more thing and it helped alot. My wastegate braket was missing one bolt and the other one was loose there for it moved about an inch when it opened causing it to open early <fixed that> I thought everything was good until i drove it on my lunch break and i floored it at 2k rpm at like 37mph in 4th gear well i was at full boost but it wasnt pulling at all kinda like bogging but after 4k rpm it kicked in it went from 7psi to 10psi it is only suppose to go to 7psi but the turbo is spooling at low rpms full boost but not responding.And when i start my car either gas or condensation blowns out at first my car is kept in a garage and it had been between 30-60 degrees out at night so i was thinking it wasnt condensation. i thought maybe gas would that make my car run rich or lean. I have ngk bkr7e plugs gapped at .30 i have had them in for about a week. If i am running lean or rich what can i do to fix that will a safc controll it or just tell me whats going on. thanks in advance to any help

Can you verify if you're running rich or lean? I would think that with the boost spike it would be wastegate related. Maybe the bolt shook loose again.

no the bolts are not loose or out i just tightened them yesterday but the waste gate could be bad it seems to be opening early still i dont know how to tell if it running rich or lean pull the plugs thats all i can do i dont have a safc or any a/f gauge or controller

ok i did my first oil change tonight 4 quarts of 10w-30 mobile 1 full synthetic and 1 quart of lucas stabalizer and a k&n filter what i always use besides the lucas first time with that. i went ahead looked over everything i pulled my plugs and this is what they looked like
#1 tip was lightish grey at very end and whitish around the curve
#2 same
#3 a little darker gray at the end lighter gray at the curve
#4 silver/dark gray and tip and tanish on the corner
-all the plugs are gapped at .30 and ar carboned up at the end of the threads but not on the electrod.
-I have a koyo aluminum radiator and my greddy vspl fmic sits about 5 inches from it and there are 3 black areas about the size of 2 softballs. It seemed like oil w/ road debree on it. when i had my redtop sr in there was only one spot now theres 3. could it be oil coming out of my intercooler fins since 2 spots on my radiator are ant the top.???? thatzsumconfusingshiat let me know if anyone has encountered that on theres

alright i got my car running right now i think all i need is a fpr to be perfect i got my car dynoed at 222whp 197 torque found i could use a little less fuel the air/fuel ratio was about 11.5. Also one of my friends rode with me b/c my car was running like shiat on the way up and we advanced my timing and it runs great now.
