Im sorry to dissapoint some of you, but if you have a top mount intercooler and dont wrap your d.p your going to bake the IC pvoven fact time and time again. Engine temps can make and break performance of any engine.

I think you got taken behind the wood shead and are feeling the spliners of dads wooden paddle. or you paid alot of $$ for a piggyback and possibly poor tuning. And i have never heard of play in a wastegate before this is new to me and i have played with them for years. wastegate problems often lead to over boosting so im going to rule that one out on this however.

DISCLAMIER- I have no opinion on masrto other than ecutec not what i am looking for in a managment set up, i do not know for fact that anything said about the tuning is to be true or flase. but there is alot of negativity about the tuning both local and on this forum. Just something to consider cavy...
