Engine Performance programmers

[bjs619]

I am looking to invest into a engine programmer for my 2011 Sierra. I swapped out the exhaust to a magnaflow and replaced the intake to a K&M CAI, I am considering a new mass air flow sensor and other upgrades but I thought a programmer would be the next step to increase power when towing and increase fuel effeciency for daily driving. Looking for some experienced advise and suggestions.

Best Thing To Do Is To Get A Custom Tune. Very Specific For Your Truck.

I'm happy with the Diablosport Intune on the canned 93 tune, and some other tweaks. Much better now after the tune due to no AFM, firmer transmission shifts, and no top speed limiter.

im in the same boat. I have a 2008 with k&n intake with mbrp exhast. Will probably have the truck for another 2 years and wondering if I should go with tune or diablo or hypertech. This truck needs more balls. For over 300hp I am not that impressed.

Tunes Help These Trucks Alot. Gears Would Be A Good Choice. 3.73 Or 4.10

I have a Diablo InTune, with original box, cables, and vehicle sticker. Send me a PM with an offer if you want it. I got it a few months ago. It is already de-registered from my vehicle and in the box and ready to go if anyone wants it. Paypal will work.

DO NOT put in an aftermarket MAF!
