Lose boost with Diablo program

Hi everybody.
Good site, found out what causes my 2005 6.0 to get the farts when I let off the pedal.
New question. I have a Diablo Sport Predator, use the 60hp program and 3 different times (cold) the boost wouldn't work. 1st time I took the program out to take in for service, started working after I restarted the engine. The other 2 times I had to take out the program to get it to work. Diablo said it was a waste gate problem. Don't think it has one does it. Anybody got any ideas.

DITCH the diablo, there junk, get a sct, they are the only way to go, we sell them and there are may=ny others on here that do, not trying to sell you something but that think is BAD for your truck

What Robert said.

SCT hands down, is the best thing out there for the 6.0. You can get exactly the tunes you are looking for. Economy, Tow, Street, Race, Just Tranny...the options are endless.


PS - The 6.0 does not have a wastegate, it has a VGT(Variable Geometry Turbo). Anybody who is tuning your truck and doesn't know that needs to stop getting your business.

For the love of God, take that Diablo and throw it in front of a train before you blow your head gaskets. I had one and switched to the SCT and wow, best money I spent on my truck to date.

I agree with the SCT being far superior to the Diablosport but his issue might be hardware, not programmer related. Throwing an SCT at it won't necessarily solve his issues...:shrug:

Sounds like sticky vanes to me, my 03 did the same thing... It won't do this at all when set to stock, even after a cold start? Could your issue be fixing itself because the motor is somewhat warm when you program it back to stock and your vanes free up. :

I'll check into the SCT
One time it was warm the other I set it back cold.
I just bet the dealer will blame the Diablosport and that's were I bought it.
Thanks for the replies
