I see that the 2006 H2 is now supported by the Trinity. I currently have the Predator Programmer for my truck. Is there any benefit to change to the Trinity?
Thanks,
Mike

Thank you.

Does anyone know the specific differences on the preloaded tunes on U7192 with latest 9rXX revisions? Are there any specifics on how much power / torque is added or not added? The descriptions on the Tool aren't very specific.

Can anyone post their custom tune that works on the H2? What to change and what not to?

I go between Mobil and Shell. Thanks for the info, I'll give that a try.

I have an 06 H2 w/ the Granatelli MAF, K&N Intake and Bassani Exhaust. With the 87 Tune installed I get alot of pinging or knocking as if the octane isn't high enough. I thought it might be the MAF so I took it out and put the OEM back in and it still did it ? Now when I re-installed the Granatelli ...

No, more so when driving. Either when coming to a slow roll and then accellerating. It just doesn't seem to accellerate or kick down quickly like it did on the stock tune? I live in the hills and my street is a hill that winds around up to my house. I'll be going uphill about 35-40 mph, slow down ...

Hello,

I have installed the 87 tune and Performance tunes and I still get a throttle hesitation. If I set it back to stock programming the hesitation goes away? I have K&N intake with the Granitelli MAF and Borla cat back. Any ideas?

Thanks, I will give it a try.

I have a Hummer H2 w/ cat back exhaust, intake and Granitelli MAF. When I install either the 87 tune or the performance tune my display on the truck shows "Decreased Engine Power" and seems to have less throttle response?
Can you help me manually tune it? Or is there something wrong with the tuner ...
