Heffner Performance would be the logical choice. They have done a couple of Gallardos so far. His shop is a few minutes away from where I live, been there for some minor mods, test pipes and exhaust. I have seen the tt gallardo, test drove it for about an hour, it is an amazing car, the fastest I have ever driven. The clutch issues for the tt G have been resolved, they are using the stock 06 clutch which is performing well.
