Short.
You are going to have to buy a clutch with an injector and box combo because the stock clutch cannot hold alot of torque at low RPM (-2,100RPM)
My truck has DD1's PE COMP, South Bend Clutch MU 0090 Con OFE, gauges, BHAF, and a custom exhaust.
Besides the exhaust being way loud, (I like it

) I think I have the perfect towing/hotrodding setup. Asking around here at the TDR I am rumored to be at 375RWHP,, I can tell you right now, that with my 2wd 3500 Quad Cab truck, with a fiberglass camper, subwoofers,, and a bunch of junk in the bed (including a rubber bed mat, and a gooseneck hitch rated for 30,000Lbs) it is more than enough to beat a Chevy Duramax with the Allison transmission.
I have raced againt my Dad's truck, a 2001 Chevy Duramax/Allison 2wd, QC Long bed 3500. Beat him bad,, actually,, beat him bad three times. The only gear we stay level in is right when we take off,, He power brakes his truck, and I launch at ~1,900-~2,100RPM and roll into WOT,, but when I shift to 3rd, I absolutely dust him,, at the end of 3rd gear he is about level with my rear bumper, and the WOT 3rd-4th shift I leave him about 3-4 car lengths behind, at 70MPH, I let off the pedal,, 'cause the speed limit was 45MPH.
The Second D-Max/Allison I raced was a 4wd Short bed, and I could have sworn it was a QC (not 4-door) I took off at idle in 2nd gear, and when I heard him go WOT, I went WOT, we stayed together for my entire 2nd gear, and when I shifted to 3rd, I just started whoopin' his rear,, when I did my WOT 3rd-4th shift I just left him about 3 car lengths behind, and when I went to 5th gear, he was getting smaller and smaller in my rear view mirror,, at this point I jumped on my brakes to slow down for a redlight that was in a 35MPH zone, and I was doing about 75-80MPH,, lets say,, I had to stop fast, and I thouroughly whooped his a... He drove away with his tailpipe between his axles...
Both of these races I was seeing EGT in the 1400-1500* area,, also WOT at 80-90MPH I get 1450* EGT,, If I BARELY back off the throttle I get about 200-300* less EGT,, , but that's no fun, LOL
I can also tow with this setup, all I have to do is turn my PE COMP off and the EGT will be very safe, even under sustained WOT. With my COMP box off and my wastegate disabled (via boost elbow) EGT doesn't go above 1000*, even in 100*F temps. I see about 20Lbs of boost WOT towing with PE COMP off.
Here's my two pennies worth of thoughts,, and a whole bunch of fun experiances

LOL
