I agree your 60' needs some work, i run sub 2.4s. keep it in drive the whole time. What i do is hold the brake down and rev my engine up to about 2-2.5k (not sure if this is too good for the tranny) but then when it goes green release the brake and slowly ease into it. your tires should chirp a little but not squeal/spin. also DA may have something to do with bad times.
