Diablo Predator Concerns!!!

Well, after reading some post's on this site about the Predator "zero'ing" out the TM. I decided to program mine back to stock until some more light is shed on this discovery. I have the 2wd, but I don't want to mess up the tranny. I drove around for a while with it back at stock, and let me say this. After having the "Diablo Tune" for a few months, and then programming it back to stock there is a significant difference. The Diablo certainly made it quicker, and I hate knowing that my truck is slower!! But I guess its better to be safe than sorry. The shift from 1-2 is so much "wimpier". The "firm" neck snapping shift is gone. I like it better with the tune, but I guess that explains the TM being zeroed out. TIME FOR THE VECTOR TUNE!!!!!

The diablo does nothing for the transmission. It's not connected at all to the transmission.

P.S. the torque management is not possible to be turned of with the Diablo on the TBSS. Put your tune back in. It's only an engine tune and will not hurt a thing.

Pssst the ECM has the lookup table for spark to retard for TM which is zeroed out.. So yes this is why people get "better" shifts with just a "ECM" tune lol So in actuality rather than tune the TCM the proper way they just wiped the TM table, kind of like the loader that they didnt engineer to query modules correctly so you dont have to pull fuses lol

So what's the bottom line Tony? Is the Diablo a piece or what?

More like just "half a tune" with a botched way of removing TM... And BTW, he's Chris...

I would not say the Diablo is a POS. But I will say it will not go into any of my vehicles. I prefer custom tunes. Or in this case Chris' tune.

That didn't turn out as ugly as I thought it would.. Take the first row of titles "%.... 10.... 20...." and shift them to their appropriate column.
