What's the best tuner and upgrades for my 2012 6.2. Is it even worth it?

 

When I was looking for a tuner, the only one that really came up was 5 Star tuning. I ended up buying the SCT 7015 from them with 3 tunes, economy, daily tow, and performance, all with the 87 octane.

The biggest change was the shifting.. I doubt it makes anymore power if any.. but it does shift so much better, it holds the gears just alittle longer which is really nice that it doesnt shift into 6th and then back into 5th all the time.

One benefit is that you can adjust tire size and tpms sensors and a few other things.

Thanks. I'm just wanting to get everything I can out of it.

 

If you search, gears make the biggest performance improvement. Put your $400 of a tuner towards 4.30's.

 

There is a thread in here about someone turboing a 6.2(didn't work out), but he did a base dyno runs before turboing, stock and with his 5 star performance tune. It equaled all of 5 hp, I'm not ******* 5 star, they get great reviews on here and I will eventually have one. But the performance you will feel come from shift strategies and really waking up the lazy throttle by wire. This has been my experience on 3 vehicles with throttle by wire and two different tuners.

 

being in 5th gear at 40mph instead of 6th has the rpm higher which means more performance. tuner is great. truck pulls so much better at almost any speed when accelerating

 

You'll defiantly see an improvement with a tuner. I wasnt impressed with my 2016 until i added one. Now it feels "right"...if that makes sense.

 

I was just going to mention 5Star as well. Lots of guys use the 5 Star tuning and are happy with it. I believe that you get 3 tunes with the programmer. Their great with their customer support too , so dont think you can go wrong with getting tunes from them

 

I remember that and the pics from the thread and some of the dyno results, it looked like a beast under the hood. If I recall right their were some issues that didnt get worked out and I think the Op of that truck and thread wasnt too pleased about it. Too bad though it looked awesome

EDIT: Found the thread where the truck with the turbos in it was for those who are curious:

The outright power increase of tuners isn't great but these trucks "feel" much better with a tuner. I drive both a 3.73 and 4.30 geared company 6.2s. The 3.73 geared truck is "quicker". Really don't know why that is?

 

I've said it on here before, I have a 3.73 truck, my dad has a 4.30 truck. His feels much better under light acceleration and is responsive. But at full throttle, his definitely isn't any quicker than mine. The 6.2 builds power up high, and the 3.73 allows the motor to stay in the upper Rpms longer where it is making the power. This is probably why the 3.73 is the default gear. But under light acceleration and towing in the upper gears, the 4.30's shine.

 

I think the real difference in "feel" in the tuned trucks is changes in shift points, and the throttle position isn't limited at low rpm's like in the factory "tune".

Just from my reading on the forums here, don't have a tuner myself.

 

I believe you are correct for the most part, but their does seem to be good performance improvements especially on the higher octane tunes.
I have the SCT X4 with 5star tunes. It really woke my truck up. I run the 87 towing tune every day and when towing my small flat bed trailer with my SXS. I run the 91 towing tune when towing my toy hauler (10,000lbs +). I lose about 1mpg with the 87 tune unloaded, but it's about the same milage as stock while towing. With the 91 tune the milage is about the same as stock but you can really tell a difference in power when towing. If used for towing I would get the 5star towing tunes and maybe the 87 fuel milage tune and forget any of the performance tunes. I got the 91 performance tune and needs work as it didn't run right, transmission shift points seem to be off.

 

It seems to me that you can accomplish most of what the tuner does by using manual shifting mode. Most agree that tuners don't influence mpg and many have pointed out that they are not happy with the new shifting points of some tunes. If you want to improve performance while towing or with larger tires, going to the 4.30 gears is a better investment.

 

One thing gears will not do is wake up the sleepy throttle by wire and the sometimes delayed downshift that a tuner will take care of.
