OP, you're running pretty good time. Nothing wrong with your 60' imo. Its tough to do much better than a 2.0-2.1 on street tires without some LCAs, etc. The only thing I would suggest to you is that you may want to try shifting a little more aggressively to get your trap up and your ET down a tenth or two. I shift at 6k-6500k rpms and I don't let off the throttle at all while shifting, except for when I engage 2nd gear. I also have 4.10s, so you may be able to nail 2nd a lot harder than I can. Just keep visiting the track and drive it like you mean business.

 

The more mods you do for power - you are only going to get worst. Your problem is not your mods - it's your rubber. Taking street tires to the track is like taking sand to the beach... pointless.

 

I have basically the same car......I run a fairly consistent 13.7. My 13.5 is at 45 degrees out at Milan without powershifting. I try to shift at 5800 rpm. Do you have a auto or manual? 2.1 60 ft is ok. What track were you at? Please don't say Lapeer.
