Running a WAI through the wringer

[Project84]

I worry about cruise control with increased IAT. Why? Because there's no secret in the reduction of engine power/performance while a HAI is in place and up to temp... thus, using cruise will require more fuel to power the car at the same rate as not using the HAI. As I think CC is wastefull in itself (excess fuel/throttle used as viewed using a vacuum gauge hooked up to manifold vac while on interstate), how much more wastefull will the computer be (fuel control wise) to compensate for the IAT's 60-70*F above what its used to reading?

Yes, you have to add more foot pressure when not in cruise while running a HAI so you'd say it all evens out, but I'm just saying, hypermilers do it w/o cruise to achieve best results... I think cruise will skew the results a bit.

Honestly?

I'm trying to be a stickler. I have my reasons.
