auto-needing wheel speed
I just pulled my truck the other night at hillsboro for the first time since some injectors, delivery valves and a new turbo. I was very dissapointed in my lousy distance of 203ft. I have been just starting out in 1st-4lo and shifting to second after I get rolling and rpm's up and just staying in second. I think i should have went ahead and went to 3rd though because my wheel speed was not enough. My question is what else should I look at as a way to get some more wheel speed out of this auto. I have been told not to go to 4hi until i get the updated output shaft and not to power brake the truck with the dana 70 I have in it. I guess if you had one or the other to do which would you do fist? Should I also stay with the 3.54gears or go to 4.10's? I'm thinking to try to shift to 3rd next time and put an 80 in the truck so I can build boost and get out of the hole stronger. It sucks to watch a duramax with less raw power come out of the hole in 1st- 4hi after ten lbs of boost squealin the tires and leave it first to put 40ft on me.  Matt
