I got the gear but now when I race from a roll, it seems slower. It'll drop down to the lower gear but the rpm's are too high and the other guy always starts to pull on me because his rpm's are still going up. Is there something i can do like changing the shift points? I went with the 3:73 gear. One thing I can say is taking off from a dead stop is greatly improved by like 200 fold. And one last thing, how do i recalibrate my speedometer? Thanks You Guys! Nathan

You need to.. A) Stop racing from a roll, that's for people who make no power B) Get a chip (to change shift points) and a speedometer gear (to fix your speedometer) from Dennis Reinhart at http://www.reinhartautomotive.com He's the only one I know of that sells both. Call him up and tell him you have switched to 3.73's and he'll hook you up. You can see how to swap the speedometer gear here http://www.tccoa.com/articles/gears/speedo.html I just won a 2003 Cobra 3.73 with trac-lok pumpkin so I'll be doing this swap as soon as I get the right speedometer gear and chip. (My diablo chip only changes WOT shift points)
