the issue is....

you hit boost sooner and the ECU doesnt know why. so it pulls time`ing, and in some cases will fuel cut. but if your going to get tune`d do it. if you get your car tuned with it on there, there wont be any issues. if you get tuned then put the heat wrapp on you will have issues.


and the miles you put on the car befor it is tuned should be very easy miles anyway. you shouldnt see any boost at all
