im realy considering it, i have a 255 pump, 30lb injectors, and i need to be retuned any way, i think the 30lb'ers should be enought, but if its close, i could up the fuel pressure a few pounds too................
04Sleeper: You and your freind only increased the timing after switching to E85, or did you up the boost too? You are making great power, but I bet you could still up the boost if you have enough fuel capacity to feed it. I ran 25psi, but only because the turbo was useless and out of breath above that.
My friend increased his timing from 21 degrees to 24 degrees total. He is running 22 psi. No boost change.
I went from 18 psi and 17 degrees timing to 20 psi and 23 degrees timing.
20 PSI is it for me with my current blower/pulley set up with my Gen 1 Whipple. I am not willing to switch my lower pulley set up from stock and I have the smallest upper pulley made on the blower. 2.60".
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
