Sorry guys, I have read so many different threads on this matter from the past. I cant really figure this out and I have other things to spend the $ on first (suspension, paint, etc.) Although this is priority to me if needed. I am trying to build a nice little runner, but a VERY solid one. I am new to the forums, but have been lurking for years. Is it or is it not time for the FC. I figured best to ask around on here.

She is only set at 6 on the boost right now and pulling nice. To me she is pulling like a perfect condition stock (from what I recall it feeling ) I will be putting her back to the 10 8 10 after the IC upgrade.

Pettit intercooler is to be installed

Goal is 300-325 ish to the wheels of possible

is it time for a FC? I am ready to pull the trigger on an Apexi, I just wanted to stop in and ask some advice before. I am giving serious thought to an AFR gauge. Should I just leave it up to the guys at pettit to decide? I am just scared to run lean, even with keeping the boost down. I am paranoid I guess.
I ran a na fc to 198k 1986
I had an 86 TII that I just started to mod and sold all for flight school. This is going back many many years. I just never got that involved in the turbos yo really know wth is going on.
