1986 SC TII swap with 555 3.87 GR
Cheap 2.5 exhaust w/ no cat and a can muffler
MP GLHS Stage 2 LM
Gvalved to 14psi


In the not to distant future its getting a 3'' DP and exhaust straight thru
+20%s and the boost turned up to 16-18psi

What do you think itll run as is and then with the 3'' exhaust and +20s?

14.0-14.2 with stock injectors and 14 psi, 13.2-13.5 with the 3" and 18 psi.
just guessing and assuming that your gonna have some sticky tires and at least a t2 intercooler

Yeah, Its got a T2 IC but I do need sticky tires! 1st and 2nd are useless on the street! Id be happy with 13s!
