2007 Silverado 2500HD - 3000 or 3500 pound w big truck caps

[Sailman_29]

Hi There,

I bought an inTune for my 2007 New Body Silverado 2500HD with a big commercial truck caps (7 feet high).

The load in this pick-up is about 3000 or 3500 pound always.

My goal is to save gas but want to keep this pick-up for a long time...

Should I use GPMS setting or I am better to use a stronger setting to avoid that the pick-up work too much?

Is it possible to have more informations about all the settings?

What is the GPMS setting you refer to?

Best bet would be to use the mileage booster tune.

Tank you for your answer,
Sorry I was refer to MPG Booster. If I want to try an other setting what are you suggesting?
I forgot to mention that the eingine is a 6.0 L gas 6 speeds.

I think that I need a pin calibrate the touchscreen?

Why there is 2 speed limit?

"Speed Limit 1" and "Speed Limit 2"?

set them both to the max value or to 'off'.
