    I had some questions on an earlier thread, but thought I would give a review on how the 93 canned SCTx$ tune is working on my '18 auto GT. I really like the tune and there is more low end torque as well as more power at top. I now get fast shifts in Sport with the paddle shifters even from 1st to 2nd and downshifting in those gears as well. The car with the 355 gears will break the tires loose at 50 mph. This thing is really, really fast. I am in awe with the whole car. The tune is icing on the cake.

    If you have access to e85 in your area definitely consider getting a custom tune for it from one of the majors (AED, Lund, PBD) You can use the device you already have and the performance will be night and day. If you're impressed with the car now just wait :)

    I am planning on it eventually. I cannot believe the performance of this car. Thanks.

    You need new tires if this is even near true

    Of course it's true. The traction control goes off indicating the tires have slipped. The current tires are Pirelli A/S 235/50-19 with good tread. Nailing the car it downshifts. I don't know about your car.

    235 tire?? No wonder you're slipping at 50 mph...

    CAI and tune would break the tires loose doing a 40 roll on my 2018 GTPP (MPS4s). 40 rolls turned into a spin fest with my race gas tune. Just FYI.
