Who has a stock lbz with his tunes? I am thinking about trying his stock trans lbz tunes and would like some feedback before spending the money.. I did a search and just got a lot of people saying to try him, no really rhyme or reason to it.

Thanks, Dylan

Well I just made my order. I run duramaxtuner on my pullin truck and if I am happy with these I may switch and have him do the puller too!

You won't be disappointed. I have had his tunes for almost a year, love them. Don't have anything to really compare against, but i love the improved throttle response, quick outta the hole, and the power is seamless through the gears. Just a whole lotta pull. I have a couple vids on YouTube, minor boosted 4 wheel launches on the optimized stock, 90 and 150 tunes. Search Dajokrz.

I'm headed to Calgary for the weekend. Would love to find a dyno for a couple pulls just cause lol

I installed his tunes in a lly and a lmm and both were great. Smooth power. The lmm was a dually and on tune 5 from a 15mph roll broke loose and got a little sideways:rolleyes:

Wow, that's good, mine made it 2k miles 14k on the truck, and it started shuttering on the 100 hp tune.

Do the 6 speeds ever limp mode or just slip the converter? Is torque converter shudder best explained as the entire truck shaking when it's got a load pullin hills?

Mine has only shuttered once pulling my camper and I was WOT at 85 uphill on my tow tune, I run my 60/100 tunes all the time and once in a while on 4/5. I cant limp it, but it shutters hard at times on the bigger tunes. Yes, it feels like the whole truck is shaking and you'll see a 200-300 rpm spike.

Mine shuddered for a good 6 months before I limped it. Then months went by before I limped it again last week. It had a hard life on the 150 tune with my lead foot. Not bad for almost 200k. Back on stock till trans is built though :/
