Yes using the recirc valve for idle and was going to try controlling valve with ecm, only closing after i get past a certain throttle percentage. thought about having valve start to close at maybe 20-30% and fully closed or max programmed boost at 60-70% and above (just estimated numbers) My reasoning is i want the option to be lite on the throttle and get better gas mileage, if at all possible. probly wont make much pressure till a certain rpm anyway but I'm just experimenting. I do have a blow off valve too. And thanks for reminding me about the heat
