Just having a TB spacer makes me want to say FAIL...

Seriously, whose tunes are you running? Many of your mods are worthless for power on a NA engine but for the ones that DO give you gains, you should be turning in much better numbers. Personally, I think some of those mods could be hindering you if they're not set-up properly and the tune must be written precisely for most of your mods (which leaves little margin for error compared to someone that's bone stock with just a CAI & custom tune).

12.35@109 Whats wrong with that? Tires wont spin? ......did they always spin after the cam install? After my cam install I couldnt get the tires to spin at all. Thats how much low end I lost.

Wow, I need my eyes checked. When I read that last night I thought I saw 13.35.
