Got my first 5.3(l59) and I love it to death. I don't have any real performance shops in town so I was curious what would be the best route for getting a tune. I don't want to break the bank but I want quicker gear changes (without stress to tranny) and maybe +20flb torque. I'm totally new to custom tunes and just want something easy to understand (plug and play) thanks in advance!

The L59 has the upgraded fuel injectors :)

You're right Bryan, at least I am hoping it is more enjoyable to drive home. I'll let you know how it goes. Thanks for your comment.

Do any of these tunes do anything for mpg?

It can, but not by much. It isnt a diesel. Biggest help is combined with a tune, properly inflated tires, driving sensibly, and not speeding

I agree I had a diablo sport hand held on my 09 5.3 and it did absolutely nothing for mpg even though the company says it does

Im not too impressed with the power..I have 5.3 w 3.42s..thinking about getting it tuned for more power and throttle response..

Any results from anyone whos done it?

40 hp sounds good)

 

In the same boat myself. I plan on a tune, CAI, and exhaust. Should bring it more to the 380hp range. There is such a delay to the throttle response :(

      The Peckish Synapse

      One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...

      L8S For 2027

      By C/K Man · Posted

      'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine.

      New Duramax rumor?

      New engines will still be using DEF. You just won't have the limp modes occurring when you run out of DEF now.

      first oil change - 2026 2500HD gas

      I am not a NOCO fan for a charger I would leave on a battery 24/7. The reason is, it doesn't really float. It waits until the battery drops to a certain voltage and then charges it back up to 14V. It's better than no charger I guess.

      I would never do anything but lithium.   If the vehicle is stored, just turn the disconnect off. My batteries are completely disconnected form everything in the trailer when my disconnect is off. Trailers don't always come that way as some still keep the CO/LPG monitor on. When mine is off...it is off.   As far as storage temps, LiFePO4 are good down to -20°C. I would store them in a heated place if it goes below that. You can also get heating mats with a thermostat if power is available.   The way the heaters work, if it's below 0°C, if a charge comes in, it is directed entirely to the heater until the battery gets above 0°C and then it allows the charge to go to the battery.   For my Android tablet I use as a display, I can move it inside my house if I was ever in an area that got super cold.
