My only question is, how big of a shot is recommended for use on a stock motor with no internal forged work without causing engine damage? I'm probably only going to use the NOS at the track once a month and maybe only 2-3 times off the track while getting on to the highway.
About Tuners, I don't nessisarily want to drop an excess of $300+ on one when I'm basically only going to download a few tunes and therefore wouldnt really use it again unless a future modification would require one or if i ever decided to erase them due to any sort of problem (MIL, etc...). So my question is, if I find someone who has a tuner (the one that plugs in to the OBDII port incase theres any question about which type of tuner I'm talking about), could I use their tuner to download tunes on to my car if they either drive a different year or a V6 mustang, or even an entire different car altogether as long as their vehicle has OBDII so that I can plug mine in? I just don't want to spend so much money on a tuner when first of all, I'm saving for a NOS kit, and second, I'd download a few tunes and then simply set the tuner aside for months.....
