hey ive come up with a problem that i heard can be fixed by rewireing the MAF... so lets say your doing regular driving around and when ever u get to boost you car just starts to bog and have a loss of all power.. and my boost gauge stays on 0.. im going to be rewireing the maf today so well see if its that.. if not wha else could it be?

hmmm i had a similar problem does your car buck when the turbo should start to boost. if so u have a boost leak. mine seemed like a totally different problem but i got my smic tanks welded and it runs like a champ now.

yeah it sounds like a boost leak. to check it go over all your intercooler piping to check any visual breaks or leaks. if its small someone had a post up here about a do it yourself bost leak tester just search its all over the forum. i was lucky enough that i just saw that my core was seperated from my end tank and got it fixed
