your going to need some more mods
A good friend of mine had that identical combo a long time ago and on street tires he was getting 2.0 60's and I think 13.68 was the best he got out of that combo and that was with an old grand prix store pcm, this was back in 03 so there werent a lot of options yet! The car ran a lot of 13.8s with that combo and one very cool night he got a few 13.7s and then the 13.68. There are a few freak cars out there that will do a little better but you are going to need more mods to get into a consistant low 13 second range. A full size intercooler will definately put you there but that is a pretty expensive upgrade for most people but one that helps out a lot-especially with a matching tune to take advantage of it. We added a full size intercooler and 2.8 pulley later that year and he ran consistant 13.2s-13.3s on street tires. HPTuners came out spring of 04 and we bought one of the first available for these cars and with tuning and putting slicks on the car we ran a 12.77 at 106. This was with ZZPs first version IC and matching blower housing and there have been numorous changes of improvement since then. Slicks alone are typically worth a solid .2-.4 improvement in ET from what I see on these cars, or more if you cant launch decent on street tires.
i ran 13.6 @ 103mph on street tires 18x9 bullitt 255/45. with half a tank of gas and throwing a code was running lean on bank 1, but i have more mods than you tho. i'm not consistent on my launching technique yet either. after my stage ic and retune by trannyman this weekend i will back to the track again. i want low 12 myself.
