I've got 20" rims with 31" tires with a 3.23 GR and I can't get my tires to spin at all. even with a brake stand

 

I got the same wheel tire size, actually thanks for the tire measurements I'm off a tad lol! I have no problem smoking till third, it's probably that tq management thing.

 

can i fix that with my programmer?

 

You should be able to with the predator, many people on the site have lessened it thru their programmers.

 

yes the predator can reduce torque management... your gear ratio isn't helping any though

 

how do i cahnge my gear ratio to make it better?

 

take it to a shop, but plan on $800-$1000 per axle to get it done. You don't want to do it yourself as it is easy to screw it up.

 

From a dead stop I'll roast the tires.The TM is reduced in the Diablo tunes just enough where it won't kill ur tranny.You can also turn the TM completely off with the Predator,just go 2 ur parameters menu,go down to Torque Management,set the first two settings to off and leave the third setting on.I have no problem spinning my tires suprised why u can't hope this helps

 

I did this on mine with a Predator. Go to "Modify Current Tune" then "Torque Managment" and turn the Abuse Mode to "Off" and the Torque vs RPM % to "Off". Leave Upshift Torque reduction "On". Test drive it > Smash the gas > let off. If it starts shifting too hard you need to go into "WOT Pressure" and "Part Throttle Pressure" and back it off a little. (By about -2 to -5 each time for each gear change [1>2, 2>3, 3>4]). Just keep messing with the shift pressures until it feels just right. Do not let the transmission slip too much when shifting. This wears it out faster. Removing Torque Managment like this will make the truck come alive. IF YOU DRIVE LIKE AN *** YOUR SH*T WILL BREAK SO DRIVE CAREFULLY!!!
