Why so little reviews so far? Is it a popular upgrade or just for a niche market? I want to know more about it! 😬

I got this tune when it first came out. My car has the carbon trap removed and an H-pipe. Stock otherwise. I’m unable to use it. Car shifted up and down randomly, sometimes shifted at 5000 rpms under full throttle. Removed the tune. Tried it again at a track day in track mode. Transmission always short shifted and sometimes actually bogged down like an old carburetor! Had to remove it again. Wish it worked for me!

I should probably contact them again and see if there’s an updated version…

Are you updating the tuner? I update my SCT X4 every couple of weeks using device updater from bully.
