Well, my T/A is already modded and was already running close to 11's on motor, with only a few minor mods.
However, my friend just added a front mount intercooler and a better boost controller. He says at stock boost with the front mount, it is NICE, and he cant wait to get some race gas in the car to crank up the boost.
Either way, my car is in the shop as we speak getting MORE, serious work done. I don't think I'd have a problem with him untill he goes single. And even then, I'll probably put up a good fight (on motor too)
