Ran at Speedworld yesterday morning with stock 245 bridgestones on OEM 16" aluminum rims weighing 18lbs each. removed tailgate, backseat, front passenger seat, 1/4 of fuel, tires at 28psi rear and 32psi front. i was spraying 60% methanol, 1200ML/min. and my egt's were just under 1600*. I made some trans adjustments, and i was shifting at 3600rpm, but i bumped it up to 3800, and I think thats what helped the most aside from the lighter tires/wheels. Im still running the stock turbo, and stock injectors, and still have more left in the sticks. Turbo is giving up.

Major differences from my 12.71 to my 12.64 were: 10% more methanol per gallon, front and back seats gone, and 200rpm more to play with for shifts. I only ran twice, because the track was packed from the northern arizona shootout guys. I still had a blast seeing them run.
now for the time...


12.64 @ 107.52
60'-1.69

Nice runs

You should try and lower the boost you may gain some the drive pressure is got to be really high running that psi on the stocker

Nice runs Brian.

I agree with Skintback though, I'd lower your minimum vane pos a little bit in that tune.

Thanks nick and Skinback.
Ive been messing around with the min vane posistions for a while now, It has lowered a little bit, but not much, but it's working. Im very surprised how much i gained from running this tune :D
