yes...on my old stang i put a LS1 computer on it and tuned it i forget what software it was but i could pretty much do anything with it...advance or retard timing it was bout every 500 rpm u could adjust it...i was just wondering if anyone has used this software i thought it would be good cause the way it is you can tune 2 different cars then buy bullits and tune more cars...it seemed to have same it not more options the the sct and other tuners had...
