I installed a Diablo in my 6.0 HD. Didn't get much in the first place, but now it seems as if I had less power than before. It has seemed to loose power over the last week or two. Today I tried to power brake the truck and couldn't even turn the tires- I could do that stock. Don't think it has any other problems- I only have 5k miles and checked it out over the weekend. Any suggestions? Thinking of just flashing it back stock for now till I get a Nelson tune- was going to run the Diablo til I got it, but???

 

Don't mess around with that predator. Its the devil!

 

If so clean the oil off the MAF. Unplug, remove and spray with contact cleaner untill bright again. Do not remove screen.
If this is not the case call them.
They take a hard beating on this forum but I have good results with them.

 

i had the predator and it is the devil. a big P O S is what it is. a nelson tune will by far outperform the predator any day.
