thanks in advance for looking and help you can offer.
Bone stock my 87 GN ran 14.0's @ 98mph. Stock boost, pump gas, no knock
Since then, I've added the following mods:
AFPR @ 43psi
TT 5.7 burned for 94 octane
Ls1 Maf and 3" pipe with 9" k&n
Adj wastegate
3" TA downpipe, test pipe
Dual 3" gn1 exhaust
Did new plugs, wires, spring clean
With the above, plus running 104 and 21 lbs boost (no knock), the best I could muster is 13.42 at 104. the 60 fts are 2.27. I really had to ease into it to avoid spinning and even still it would spin a bit 60 feet out. I was only gently brining it up on the converter. O2's were 800-850.
Despite the traction issues, I am still underwhelmed, since I've seen some run in the 12's.
Thoughts?
