Bought the car used and have decided to start upgrading with LTH , eurocharged tune, and possibly go e85, but before anything. i went today to put the car on the dyno for a stock baseline before the upgrades. in there expecting to be around 380 or so then surprise surprise the guy says 434 hp then changes over to the SAE and its 429 hp 414 tq so I'm guessing the car already has a tune on it lol, already ordered my tune from eurocharged and header. now I'm scared to change it and lose power , honestly can't wait to put on the headers and go e85 hopefully make over 500 to the wheels
