well i just did a tune on a guys v6 car, went up to about 10% richer wot, 6 deg more timing than stock (more seemd not to do anything) and changed some crap on the auto shifts, and it pulls pretty much alot more than a 93 tune i threw together, its all on a handheld tuner, so i couldnt really fudge everything, but fwiw: over 93 i could squeeze 3-4 more deg's more timing out of it at wot. no knocking what so ever, on the rich side as well.
gonna love it when i get the tune on my 98 4.6 lol by seeing how much it picked up over a diablo tune it should be fun
