[QUOTE="JAJ, post: 16435951, member: 131874"] Yeah. If you've got a nice, clean tip-in now, it'd be interesting to know what he changed. On the IAT2 thing, anything you can do to improve flow - headers, exhaust, cam, etc - will reduce back pressure (the thing we know as "boost") and as back pressure comes down so does temperature. A lot of folks think that higher boost is better but it's the opposite. When I was tuning my Coyote, I got boost down from 12 psi to 7 by adjusting the cam timing. Engine ran cooler, IAT2 was lower and power was unchanged. [/QUOTE]
