Re: Which AFR heads do I need?
The installed height of those injectors gonna be alright???
I was told that I would need 32's as well.....
Wanted to try to tune first..... and go from there.

First start:

Warm idle:

For the stock tune, it runs WAY better than I thought. Obviously it runs too rich with the 30lb injectors. Idles good in park @750 rpm. But the idle speed in drive/reverse is too low. The car almost wants to stall. For a stock stall, and 2.77 gears, it is not slugish off the line. I was VERY surprised. Plenty of torque too and I'm running open headers.

Re: Which AFR heads do I need?
Abit more lopey than I thought but will be a strong running car thats for sure! MAF cars can take some mods and still work somewhat ok on stock tune. Glad to see its running tho. Congrats. Very nice combination there in a very nice car.

And a big thank you to everyone else in this thread too that helped me! (Air_Adam, GTA Sammy, 1989GTATransAm)
Orr, I see you put your AFPR in the same way I did. How the heck did you get to that screw to adjust it. Looks like it's going to be a challenge for me!
