Currently tuning my car with TunePlus. I have a bunch of mods to make around 350-400 wheel. But now that he’s giving me more boost, I’m up to about 27psi now. The car keeps fluttering/stuttering all the way up in rpm. Even though my traction control is off he’s telling me that the traction system is kicking in and cutting timing. Anyone have any clue what this could be or how I can fix it? I literally can’t get the performance out of my car. Thanks.

Short press of the traction button is sport mode, long press is off. Are you turning it off?

You will also spin most all seasons, so make sure you have stickyish tires
