If you look at the top Navbar you will see a new selection called "Duramax Math" that is the new DuramaxDiesels.com ET Calculator. We will be adding more but this is the first. Pat wrote the formula for it using diesel truck math adjusting for it your truck weight etc.

One thing you have to be logged into the site to see the link.

inputted my est weight (6500) and est power (535) and it hit 12.41. IMO, Nick's tune is putting out more than the old Hot+2.

Figured 6600lbs and 545 and also got 12.40 on the nose. Its not gonna be easy to get those last .4, though.

Plan on doing a 1/8th mile calculator?

My ET comes out to about 15.56 in 1/4

I don't think my truck will do that in the 1/4.

I have run many 10.45/10.50's in the 1/8th.

Using my 1/8th to 1/4 Calc, my 1/4 ET from the calculator here, and converting to 1/8th mile ET is way off.

Using the same inputs used here in my 1/4 ET Calc, the ET after conversion, is closer to what I ran.

Using my 1/8th mile ET Calc, my time is about spot on.

I think the calculator here is a little optimistic.

15.5 is about what an LMM/LBZ CC 4x4 runs bone stock.

What's your 60' times?

Your calculator seems to be based on engine stand HP. None of us has engine stand data, we typically dyno the trucks on chassis dynos.

But it certainly works well for stock trucks going by the badge HP.
