GTM Performance Engineering: MHI Twin Turbo Official Release

Alkatraz

Correct.

I would also suggest that anyone who is going with a much larger exhaust, ie. 3" would probably be more prone to boost creep with IWG's. I haven't run a search but has there been much of a history of boost creep with 370Z/G37 TT installs? I don't remember seeing mention of it.

OP, make sure that you install a good boost gauge and set alarms. If you find that the boost is creeping consistently then you can look at either porting or swapping to EWG.

I have a feeling that once everyone starts their GTM installs and run them for a few months, we will start to see what issues are common across the setups. If 50 kits are installed then we should have several thousand miles worth of 'real world' testing done within just a few weeks.
