i took her to the 1/8 mile track last night for the first time, my best run was 8.91 with a 2.18 60' at 77.7 mph. my slowest run was 9.3 at the same mph with a 2.4 60'. its a 2wd.... so that tells me its all in the 60' times.

so i guess i need help with launching it, there must be a better technique as my 60' times sucked ass. i set my staging with efilive to 15-1600, and leave at 40-50% throttle, try my best to roll into slowly, usually shifting into 2nd at 80% pedal then floor it once its done with either axle hop or spinning during the shift. id like to know how the other 2wd guys launch to figure out a better way. i was also thinking about airing down the tires, will this make a decent difference? i felt the g80 let go halfway through every burnout, this makes me think im probably getting a one wheel peel off the line. is there any hope for the g80 with maybe some fresh fluid, is it worn out or do they just suck? i considered a 2nd gear start, but i figure that would be a bad idea with a stock converter... as for weight reduction, i have a huge peice of steel the previouse owner used as a home made 5th wheel hitch, i could probably drop 200 lbs losing this and the tailgate but will that do more harm then good being that the weight is over and behind the axle?

Airing down would help, maybe start around 35 psi. Have you clamped your rear leafs? That would help launches by reducing axle wrap causing wheel hop. Just clamping the front of them is recommended for drag racing.
