So if you're considering 255's just accept it for what it is and know that you won't be putting down stellar times. You may be competitive locally in SM depending on what you have for local drivers.
Yeah, that's what I thought which is too bad. I think eventually I'll try to modify the car back down to STU to shield myself from the burden of buying A7s.

Right now the car has a bigger turbo than stock and is catless. I don't think it's responsive enough like that for autox anyways and would probably be faster in the tight sections with the stock turbo. The previous owner had it built this way. Maybe when I'm ready I could find someone who would want to trade turbos.

Edit: I should also mention that the car has an IAG stage 2 short block. I'm unsure if that would also keep me out of STU if the compression ratio was not changed, and if the part is not add performance and only adds durability. If that's the case, I probably will not be going to STU ever.
