remember that launch control is not ment to be in a daily driven car
first of all, the detonation of the launch control is to spool the turbine wheel
its a sudden explosion of energy , ur car is nt a drag car , drag cars often service
their turbos, some even do it every race or season , are you prepared for that ?
2nd , exhaust temp increases, it doest nt only tear ur exhaust manifold, but it might also hurt ur pistons n etc. Lastly, if ur tuner know nuts about the function, bye bye engine
u may also fit anti lag into ur car, just prepare the cash to repair & replace ur turbos more often
totally agreed...mod ur car for good purpose....for road or track use....
