If you had a stockish truck tuned what were the results. Did you use a dyno/street tune or did you use a handheld.

I will be getting an intake an exhaust soon and would like to see what everyone has had good results with.

My brother and our tuner have tuned my uncles 2014 5.3. Made a huge difference. They used hp tuners..

My tuner already did a 2014... Did 293 baseline with just a flowmaster type muffler and finished off with 323 RWHP after a tune. These new trucks really respond well to upgrades it seems.

There have been a few... check out the section dedicated to the new platform and you will find a couple threads.

That's what I am talking about. Was it tuned for premium or 87 octane?

I'm now looking at a ported manifold, intake, catback, tune. I was hoping to be around 330ish.

I'm really anxious to see what these 6.2's are gonna put down! I think people will be surprised...or it feels like it anyways by driving one! These new 5.3's wake up a lot too with a tune. New motors are very peppy!

Yea I'm really excited to see it too. I can see myself daily driving a 14+ 6.2 with headers and a tune in the future.

Has or is anybody tuning the 4.3L V6? My work truck is a 2014 GMC Sierra 4wd CC/SB with the 4.3 V6. It has a delay in the gas pedal that I'd like to get rid of plus all the other benefits of a tune!!
