NICE!!

enjoy man!

I just got the Diablo tune installed on my 2011 Silverado. My primary reason for getting the Diablo is for improved fuel efficiency. That being said, which tune should I run? The guy at the shop said the 87 octane tune is primarily for users in the northern part of the country. Not sure what he meant by that. I would rather not have to pay for premium gas.

Thanks!

I put the 87 tune in my truck and was geting 18.9 before and after tune i get 20.1 even running hard.I love the thing,good luck.

Are the harder shifts going to be harder on the tranny and rear end? I had the back end get loose shifting into 2nd and 3rd. I love it, just want to make sure I'm not going to tear anything up.

will this update help my 4.8 or is it for 5.3 only?

you need to get your other issues straightened out first...

try putting a battery charger on your battery when you try to tune the truck man...

i just updated my u7194 to 9r20 and I tried to install it into my 2008 Silverado 5.3 non flexfuel and it said original backup not saved(-11) and it gave a reduce engine power in the instrument cluster with a few codes: p0606, p0607, u0101, u0109, u0121, u0140 and another immobilizer code. it was working fine before with one of the previous updates. please email:: [email protected]


thank you.

I am having the same issue as jrodela06 on my 2010 Camaro SS. try to install Diablo tune and it throws stablitrack error and loads the codes listed in his post. Car wont start until i clear codes.
I was on V 9.14 this morning and it worked fine.

^still have not got a correct fix from diablosport as of Thursday I was told to disconnect battery and try again, that failed so I downgraded to 9r19 and it worked like a charm.

Ill give that a try. thanks for the info. I tried to go to 18 and it wouldnt let me.

Downgrade to 9r19 worked perfect. Phone support wanted me to send it back to them. Told me that device isnt meant for downgrading??? Just an image thats flashed. Since a few of us are having this issue and my predator is only a year old i suspect they have an issue with 9R20...
Thanks again jrodela06 for the info.

is this a fixed version 20 or a faked version 19 just to get the predator downgraded to a working version?
