cooler weather will cause a lean condition if not tuned for the cooler weather........


hot air makes it more likely to detonate too............

on the stock tune i'd say in the heat is the most dangerous... but the stock tune is so damn rich anyhow, i dont think you will have trouble



also, on fords the IAT sensor controlls the A/f somewhat and the timing somewhat...


this is where the IAT resistor trick works....... but you have to keep resetting the computer, because it will always compensate after a little while.......


best thing to do is get a couple of tunes maybe? or run race gas to lessen the chance of detonation.......









OR.......... DROP A CARBED 302 IN IT.........
