Re: G6 2.4 ltr
Yeah, but I don't have one of those precise caliper measuring things. ZZP says you should see 2-7 whp from this.
Maxbore also ports the IM for 90 extra. What do you think about the power gains from letting them go to town on both the IM/TB? They say they will port both to the maximum. Doing so will probably screw the ECM though right?
