My last pass was 12.74 and so far I only can launch in 4hi, it is usless for me in 2HI, can spin the whole strip and never get traction. I'm on 24's with nitto 315-35-24

So for me at the strip the 4hi is a most.

In the street is also a need, cause, If a ricer just happen to tease me...and roll race, once the turbo hits, my truck goes butt to the left endagering everyone...so at street, if I wanna race, need 4hi too.

So long I have hit 115+ mph have not granead the front internals...YET !
I have pretty much done the same as this fella. I always launch in 4hi then switch to 2hi after the 1-2 shift. I accidently left it in 4wd on one run at the track and my trap speed was considerably lower. I have the electronic shift 4wd, seems to make a difference on the top end if you shift out. Seems that I cant launch with over 5 or 6psi of boost off the line or my truck will spin in 4wd, I got sideways in 4wd on one run at sar. I have similar mods as rutroe.
