im using the KA auto computer,

get up and go from a stop on any automatic sucks. Stall it up and it will launch harder. If you manually shift its much faster as the shift points with the KA auto computer suck.

Once the turbo kicks in my tires spin out bad. I really need a vLSD. I have the regular stock differntial and one tire spins bad. once that turbo kicks in then my tires are gone....

My 1st pulls just as hard as reverse but the reason your reverse is spinning your tires more is because you effectivley created a FWD car so it will spin out more.

stall rpm i got no clue....how do you find that out?

REVERSE WILL PULL HARDER BECAUSE IT IS A STRAIGHT CUT GEAR MOST OF THE TIME AND ITS ALOT LOWER RATIO THAN 1ST.
