Of course if you want to add tons of horse power by the most simplest means necessary, you will buy a programmer for your truck. The immediate Pros that you will experience from your purchase of this evil pleasure, is the instant gratification of extreme power. Let’s face it, depending on how much you’re willing to spend. Programmers can add horsepower in the ranges anywhere between 40 hp to 225 hp (and I’m sure there are some that do more!) Adding that to your (already 300 hp truck) can really add up. Unfortunately, all this power can turn your Allison trans into scrap if you’re not careful.

So my question is for those who have been down the road of (programmer induced) transmission damnation, or know the dangers of dabbling with the awesome power presented to us in a computer chip.

What is the maximum amount of power that we can ADD to our trucks without damaging our transmissions. These answer apply to stock transmissions only and the power must come from tuner/programmers.

Thanks you I hope to get a lot of feedback.:D

90hp?

While waiting on responces I tried searching the internet and i found a very interesting atrical from a reliable source DieselPower Mag. Here is the link to it

for an LB7 its about 100HP. some trucks youll be able to throw more at it and for some reason theyll hold up and some will limp on less than 100HP. its a crapshoot and ya gotta pay to play! but it is soooooo worth it

My trans decided that 100 HP extra was quite enough...although that was towing about 22,000 lbs. combined truck and trailer. Unloaded that tune yielded 23 mpg. I only run about a 30 HP tune now. After limping the trans about 5 or so times in 162,000 miles with different tuners it still seems to work good at this point.

90hp? yeah that rings a bell
