What would be a its expected effect on a N/A car?

You have to relocate the IAT sensor to after the meth. Your cars a/f should be tuned with out meth on and very litte timing. Once the a/f is locked down you turn on the meth and start adding timing. The more timing you add the more it will lean out which is what you want because meth is a fuel and you will run rich depending on how you mix or spray straight meth. For example I sprayed straight meth and it dropped my a/f from 12:1 to 11:1 but after getting the timing up to 24* it leaned it back out to 12:1. The last thing your tuner has to do is set the IAT temps for pulling timing. My IAT never went over 78* no matter how hot it was so the computer was set to pull 10* of timing if the IAT was over 90* and pulled 1* for every degree over 90*. If meth ever failed the car whould just have no power and give you a heads up but be completely safe.

The main thing for an NA engine is the cooling and added octane. You can run more timing. Now on a completely stock NA motor not much of a gain maybe 15hp but on a fully built high compression engine your looking at about 50-60hp gain. It works best with nitrous and FI that where you get over 100hp gains. The stuff is so good it's outlawed in just about every class of racing.

Haha, I can see why. Its like crack for F/I cars
