well first off idk how my tranny is still together. I run either the stealth 215 tune, or the ppe hot tune on any levelroflmao, now i have 20"s and 33x13.50 nitto terra grapplers....now usually when i have my transfer tank(custom made 120gal rectangle that lays over the wheels)..and i keep it 1/2-full tank... my truck will keep traction and take off like a bullet(not as fast as you guys but fast to me:woott but i sence took all that out sence i bought a littler chevy to put that in so this isnt my work truck anymore, now on my stealth 215 tune i can bake the tire completley dry pavement until 4th gear(tranny should be blown by now):rofl:...i usually launch in 2wd but i raced my dads friends 2011 camaro ss last night(what a big hype for a shitbox) anywho...basically what im asking is what type of traction bar do i need...i tow a two car hauler with two full sized offroad truck or race cars, does that come into play?
