Score! Now, when you get your car back, baby the friggin hell out of it! Do NOT open the throttle and go into boost EVER, until you get tuned. You shouldn't drive around at all, so if you can talk to your tuner, ask him if you can get a limp map so you can safely drive it til you get the proper tune.
having a cobb stage 2 will help him loads more then if he has no tune..on top of that with carfull data logging it may work anyways just fine it just depends
