I only let it slip once briefly (all too familiar), got out of the throttle and programmed it back to stock tuning.
I may have to ship my predator back - I'm not going the new clutch route.

Are the stock clutches really this close to the edge with stock power????

Basically, as it stands almost no HP increase is usable.
WOW, extreme stacker with my EZ on 3 wouldnt even slip the stocker... under normal full throttle acceleration, but I had to be a wise guy and make it slip.....

I had an identical experiance last week.

First time out i rolled into the throttle in 3rd gear and at about 2k rpms it slipped like a 300k mile burned up clutch..my truck has 19k miles on it

Only thing is i used to have a smarty and i never ran it over 90 horse, and the clutch NEVER slipped once....I even did alot of towing on the 60 and never had a slip.

I think something is up with the diablo tuner because the so called 60 horse tow tune feels like at least 100 or more


All i wanted was a mild hp increase, i think the programming must be backwards on this thing. As i have time im going to try each program and see if one of them is the tow tune. I hate to try and deal with diablo's service yet.

It's an 07 3500 5.9L with the 6spd G56.

Wow - seems everyone's clutch is holding better than mine. I thought it would hold the extra 60 ponies easily, but apparently mine is probably not all that far off not even holding stock power.

I went for the mild tune just to keep on the safe side, but had to resort to stock tune immediately.

I guess I've got to suck it up and ship my Predator back to the dealer and forget about power upgrades on this rig. Sucks, but such is life.
My clutch is toast at 32000 it slipped with the SC in tow mode dont feel like the Lone Ranger.

Ya i had a guy on here before told me i was crazy, when i said the stock clutch in front of the nv5600 would hold a LOT more than the g56. Read these guys posts with the early NVs, and my self have put big power to the stocker for sometimes years. The G56s are closer to the edge from the factory for sure. I have another friend with a 07 his sliped with the ez, thats only 65hp over factory. I ran 150hp over stock for 3 years.

i dont understand why my clutch would hold up to the smarty or 30 and 60 towing up to 24k, and 90 unloaded and never show a sign of slipping...then 15k miles later with 19k on the clock i put the supposed 60 horse diablo tow tune and the thing slips the clutch in 3rd gear half throttle?

If it was working so good for you why did you switch tuners, to hear from people on this site the smarty is the best thing since sliced bread? Just curious.

the smarty smoked way to much even in the lowest setting, it was even worse towing. I hated the smarty, it was almost impossible to drive easy without billowing smoke.

i tried the 60 horse puck tune and it feels like a 60 horse tune... no slipping clutch. there must be something programmed wrong for the 60 horse regular tune for the 7131 tuner

did you try the performance/economy setting,im not sure aboutthe 7131[i have a 7130}but the perf tune doesnt seem to have the low end grunt that the tow tune does,that may be easier on the clutch,im running it now as we get into winter season so the tires dont spin as easy in the snow.

My NV5600 slipped with just a Quad std. It was a used truck, but the mileage was low. I think there are just a lot of differences from one truck to the next.
