2011 Silverado 6.2L L9H questions

[Drivehard]

I am in the process of researching tuner options for my truck. I know the L9h from GM has lots of potential that can be unleashed with a proper tune...but with so many options out there, it is hard to know which is right.

Has specific dyno work been done on the L9H from Diablosport?
Can I adjust torque management with the InTune?
Is there a list anywhere of what parameters I can adjust with my engine and transmission?

It seems that no tuner companies are willing to tell me specifically what parameters I can adjust on my specific vehicle. It is very frustrating when trying to make a purchase decision.

Thank you!

TM can be adjusted in the TCM, we reduce it in the PCM tunes already.

You can adjust idle speed, fan settings, top speed limiter, rev limiter, shift points, shift firmness, WOT spark in 3 rpm ranges, WOT fuel in 3 rpm ranges, disable DoD (AFM), and more.

The most likely reason nobody wants to tell you what parameters they have, is because nobody offers as many end user adjustable parameters as we do

Let mew know if you have any other questions.

Thanks

"TM can be adjusted in the TCM, we reduce it in the PCM tunes already."

What is TCM?

Has any specific tuning work been done on the L9H?

PCM controls the engine, TCM controls the trans.

We have had a few 6.2 trucks on the dyno here over the years.

Sorry, hate to be a pain....

So, can I adjust TM controlled by the TCM with this tuner?

we reduce most of the TM in the TCM tunes we provide. There is also an end user adjustment for TM upshift settings in the TCM parameters.

Thanks

What were the dyno numbers from tune vs stock?
