I have worked on and tuned cars my entire life, this by far is the best/easiest thing I’ve ever bought for pure HP and TQ gains.
Best tuner software there is, easy to use and makes my TLX Type S scream.
Slow shipping but it got here either way. Undamaged and good to go, so I can’t really complain.
Highly recommend both iRACE AUTO SPORTS and KTuner for you tuning needs.
