I was wondering if the diablo sport tuner for the 06 cummins is any good i've heard it has problems but only for some people. so i was wondering if it is recommoned to buy or not . THANKS<STEV,

 

diablo is alright. . .it will give you what you want. I'll be the first to say it though, the Smarty programmer is the only one that will keep giving you surprizes even after you though there couldnt be any more. you also have the choice of more than 12 different loads each with 4 different power settings with and without timeing.

there are quite a few of us here that have one and are VERY pleased with it.

 

I have the Diablo sport predator. I love it.

 

Liken my smarty personally, my friend has a diablo....equal hp tune I can take him.....FYI
