going to ffw in epping nh this saturday. i haven't decided if i will make a pass yet. if i do, what should i expect to see? curb weight is 5689 lbs(stock), and i add another 160 lbs. it is 4wd. mods are in sig. i'm sure i will be a little hesitant being my first run in any vehicle. i should mention that i have 20's on now instead of the stock 17's, which on the dyno reduced my tourque, but somehow my hp went up. should i launch in 2wd or 4wd high, and then flip the switch as i am moving? i also have an awd choice, so maybe that is an option? i don't plan on removing anything, except maybe the spare. i run the tires at 38psi. the temp for saturday in epping is supposed to be 77* and partly cloudy. thanks in advance for any assistance.
