I just got back from the dyno and laid down 464 hp with just the mcrat race tune and TTS lift pumps I didnt get to try my own tunes because I left the laptop at home oh well they asked me back tomorrow to try some more for free. they were so impressed by the power with so little mods they want me to be a test truck with some programmers and other things if I want first will be a PPE HOT+2 :D

Depends on the dyno I suppose. The dragstrip performance on Wendy seems to back up our HP testing at Westech.

I dont think there is anything wrong with the tune I am sure it did put out 500 hp in california but that was california and this is in texas different dynos different weather conditions different dyno operators.remember dynos are just tools I was just letting everyone know what my numbers I am very happy with the tune.apparently the shop owner was very impressed as well they started telling me the laundry list of parts they have to do to a cummins to get those numbers and commented on how how he liked the new duramax.

Great numbers, congrats on your new tune, kudos to the guy who built the tune, and most of all; a satisfied customer satisfied with his tuner!

I redyno'd it today and stock it put down 274 hp so I think it is a little low the we redyno'd the mcrat tune and it was about the same number I think the dynojet dyno was just a little low shouldnt a stoc LBZ put out more than that usually.

oh yeah I dont know if I just have a wednesday tranny or what but it is standing up to more than 500rwhp dyno proven hp and it was run on the dyno for most of the day it only started slipping at the end of the day, even the shop owner was impressed saying they are waiting for me to blow it up but it kept going. All bow to the mighty allison

Wendy did 309rwhp at Westech bone stock, so you are about -10%.

Many other LBZ's have run about the same stock on a load cell dyno.

oh ya and good job i have never thought anyone has found the limits to the trucks and you are proving that even a stock tranny can hold up to the abuse

Very good numbers for a stock Allison. You may be losing 20-40 rwhp from the tranny slipping, even though you didn't notice it.

I would love to know what a PPE Hot +2 tune puts down!

I plan to run mine with a boost stick and I have exhaust and intake and a manual but it would give me a baseline.

Nice numbers! Good luck with the stock tranny:eek::

I think an exhaust would help you out a bunch!!!
