2014+ Engine & Transmission Tuning

[KARNUT]

Make sure your back to stock, my dealer ask me before messing with my truck. I just went in for an oil change, they mention the new odo recall, I told them its working stay out of the computer. I don't care if the oil change is free, I can allways do it myself, if I have to worry about them poking around, with out my consent.

They are Government Motors after all.

Yeah, just guessing by what I've done, I would say that I'm about 75% reduction on TM and shift firmness and can bark the tires, it's a little much actually but I'm just creating different levels of tunes for customers. Good to hear you are having good luck with another programmer. Hollar at me if you ever make it up around the Tulsa area, I'd like to check your tune out.

 

TDT I sent you a message in regards to tuning, let me know if it went thru.

 

The odometer recall is tuned thru the BCM and does not affect the ECM or TCM.

I'm kinda amazed at how quiet mine runs. I have the stock exhaust and the two electric fans. It's the 5.3L.

 

When I mash on it it goes, it just doesn't have that signature GM V8 scream I'm used to. Am I the only one?

These new trucks are very quiet when stock. Get a good cat-back exhaust and itll scream for you.

I don't get why unless there was a huge hp gain anyone would want a noisy truck . I love how quiet mine is.

Finally got around to loading my BB tune... one word... WOW!

 

No more AFM, the shift points are smooth and no more searching, and the truck pulls thru 98mph to infinity and beyond!

 

I've watched the mpg steadily improve over the last hundred miles from 13.4 to 13.8... If you have a 6.2L you have got to get yourself a tune!

Update no. 2 Performing as advertised, I drop the TM down to 50%, now a firm shift with out the feeling of someone hitting the truck with a sledge hammer.

Finally took a trip 500 miles so far. Started with E 85, 17 miles per gallon, switch to 93 almost 21 MPG. This is running at 72 MPH and no V4. I have 7000 miles on truck. At 3000 mile on truck I got 18 MPG, no tune and V4 on at 75 miles per hr.

This is on an Hypertech can tune max energy, set at max tune.

so has anybody gone in for service yet and been questioned on the # of flashes on the ecm with a blackbear tune ,i really want to do it but our dealers are militant up here lol

Same here, my dealer called to ask me how im enjoying my truck i mentioned the shifting could be a bit smoother and throttle response is a bit laggy down low, nothing a good tune couldnt fix to smooth things out a bit. he mentioned that they can see every flash, and when data is downloaded they know whats been done. So I called my best buddy in the northeast who runs a chevy dealership and he told me the same thing. i want to get it tuned so bad but i paid for the extended warranty and would hate to have wasted that loot

You can sell the warranty back to them. Buy the tuner and put about 1k back in the bank IMO. I didn't buy the extended on this one. I have bought it on the last 3 vehicles saying I wouldn't tune but have tuned every one of them before they turned over 5k miles. I understand everyone's situation and needs are a little different though.

I sure wouldnt call a good catback noisy. Some guys (including myself) just love that V8 exhaust note!! Music to my ears. Stock it was non-existent....I HATED how quiet it was.
