The duramax generally has a weight advantage. Also, if he has big huge tires they will slow him down. You need to get a lift pump and give that Cummins a run.
lbz vs cummins?

Might help you off the line if you yourself don't have issues. Sounds like he has the upper hand for sure.
I'm on 285s, plan on launching around 10-12psi. Like I said, I don't plan on winning haha, but it'll be fun regardless
Thats the spirt!!! Racing woukdnt be fun if you akways knew who would win. Maybe he cant drive it worth a shiz...
Rowing gears will slow him down too..... The more I read the more confidence I have that you'll give him a run for his money. If your trans isn't too hurt and you have a big enough tune it should be a close one.
The 13.2@106 I ran was on stock trans with lift pump and PPE 300 tune, and mine is CC/LB

Thought in the original post the dodge had a built trans? Built manual ain't gonna be faster it will just be stronger.
Allison cant hold that much power stock. Clutches don't slip. Gets the power to the ground. These trucks don't have a pump to feed cp3. So on a hot tune the cp3 can't suck enough fuel to supply itsel . So the lift pump takes care of that.
Lift pump helps CP3 out by giving positive pressure to it, so it is better able to keep rail pressure from dropping off as fast. This isnt a "fix" for an already weak CP3, but it does help.
Built trans, besides being able to actually handle a hotter tune, can also increase the amount of power you are actually getting to the ground. I remember years ago at Kennedy's, when Merchant built Nate's trans right there in front of everyone, they did a before/after dyno with same tuning. There was a +50hp diff with the built trans.

I mis-spoke in the original post, it is a manual but it has an aftermarket dual disc clutch. I haven't talked to the guy in a week or so, hoping to line up not this weekend but the next. Hot tune on my truck is 135hp. Is it worth airing down my tires? If so how low should they be?
