I dynod my truck sat and ended up with these numbers 437/937.. Stock stixs and cp3 holding 27k rail in my sled pulling max effort tune from ATP. 4094 stage 2, lift pump, deleted with up pipe, 3"dp, 3" cold/hot tubes and y-bridge, stock filter delete. I could only get 26lbs of boost but then got 34 on highway in 4th. Built trans also and other supporting mods.. I had more TQ then other trucks with just about 100 more hp.. A lly with built trans intake exhaust and tunes only, beat me..


I am very disapointed in my truck and not happy.. I could trade it in right now and never miss it.. But I geuss a 1/4 mile time will tell the truth.

I don't like dyno's, they are so inconsistent from shop to shop. Used as a tuning tool I'm sure there great. I wouldn't worry about numbers accept the ones you see at the track, there really the only ones that truly tell how much power your putting down, IMHO.

I just hate how I have all this money in it and a pretty much stock truck with tunes beats me.. Even a lb7 with stock sticks and cp3 but a s472 got 560 and less TQ.. The lly that beat me I don't think has a lift pump

Sounds to me like the dyno really wasn't loading your truck up good, only 26 psi of boost? I know its disappointing, but I wouldn't worry about it until I got to the track and could only run high 13's with your setup.

just put me in a bad mood all weekend so far. Before I had built trans me and my friend with his lml raced on 150hp safe trans tunes and I beat em.. Even now with his 200hp tune he won't race again lol.. Drove my truck and said no way..
to end it all I also got spanked at the truck pulls.. Just not my weekend

Who's tunes where the other trucks running? I know rob holds back on the tuning.

I put down 523/1035 on a dyno jet one weekend. Then 470/930 the next weekend on a mustang dyno. Ran it at the track and ran 12.83 at 107. Race weight was 6400. Comparing dyno numbers is a joke.

A 4094 is a tough charger to tune perfectly, it seems. Which translates into hard to load up on a dyno too. I wouldn't worry so much about the dyno as much as your e.t. and mph in 1/4 mile.

I'm thinking I should of went with a s366.. But I wanted to stay stock spearing for sled pulling.. Alligator performance said duramaxtuner really has these turbos figured out.. I just don't got a extra 650 to buy more tunes

Dyno is just a tuning tool IMO. Dynos vary from place to place. To get a true number run at the track and weigh the truck.


We dynoed 514 on a bone stock lmm this weekend with just a tune, not even a lift pump
