Most of the piggy back tuners just put a resister(.90) at radio shack, in paralell with the inlet air temp. telling the computer your engine is receiving cooler intake air, we all pray for at the track. Good for about .1 in the quarter.Not sure it would work in our speed density cars,know it did work on my mass air Cobra and Corvette.If I'm getting nice cool air, I just add a couple of degrees of initial timing and 2-3% more fuel with my Predator.
