I just bought a 2012 Ford F250 for pulling my camper I recently had my Diablo Trinity in my 2011 silverado 5.3 and kept the programmer so my question is how will it work in the F250 any problems??

Thanks I just wanted to make sure I was in the safe zone. I don't know how much difference there are between the trinity and intune canned tunes but my mileage on the 87 ocatane tune went from 14.5 to 17 mpg's I was impressed!!

I just got my diablo trinity and had the intune before I have 285/75 R18 Nitto Trail grapplers so what will be the proper height in inches it has an OD of 33" on the sidewall of the tire but when I put that in the trinity it has the speedo off by about 3mph on my Intune I entered 31" and it was ...

Hey guys Im running the 87 ocatane tune and the tranny on modify stock tune. The reason for that is it shifts so hard from 1st to 2nd and 2nd to 3rd from a dead stop to wide open throttle it feels like its about to snap the rear end!! So how do I adjust the shift pressures and which ones in TCM firm ...

I will try the positive shift pressures and see what happens thanks and Merry Christmas!

This is very frustrating spending hundreds of dollars for this programmer and it still needs to be tweeked on even using the canned tunes. I dont want to have to get a custom tune rightnow to fix my problem I just want to use the programmer but cant. I never had this problem with any of the ...

I have my 2011 silverado 1500 z71 on the 87 octane tune and it works great except shifting from 1-2, and 2-3 it shifts so hard it twists the whole truck and feels like its going to snap the rear end and tranny. I have turned the shift pressures down to -6 and still hasnt gotten any better so can ...

I am running the TCM firm shift tune and the ECM 87 octane tune I have made no adjustments to the TCM tune I will post the tunes as soon as I am off work.

How do I get my transmission to stop shifting so hard from 1st to 2nd and 2nd to 3rd? I'm using 87 octane tune with firm shift but it feels like its about to snap off the drive shaft and rear end.

Im currently using the 87 octane tune on my intune if I want to make changes to the tune do I have to return it to stock everytime I or just hit reset all parameters then tune again?

I plugged mine into my 2011 silverado straight out of the box and it worked great. I updated a day after and my stock tune stayed in as it should nothing was erased.

I am running the firm shift tune also I will make the shift pressure adjustments thanks guys!

I love the tune expect the hard jerk on the drivetrain from 2nd to 3rd it shifts a little to hard I dont want to damage anything the truck only has 27000 miles on it. I was just curious of my options.

With all of the canned tunes can you just tune the engine and not use the TCM tune on the transmission?

Thanks
