OK GUY'S I HAVE TO SHARE MY EXPERIENCE .....

OK GUY'S I HAVE TO SHARE THIS ........

Since I have tuned my 2018 5.3 Silverado with the 6L80E transmission with HP TUNERS it is literally like night and day difference!!

  1. I am now getting 2 more miles a gallon.

  2. It definitely has noticeable more power.

  3. The transmission shifts so much better and with authority, no more bogging in gear lugging the engine at 1200 rpm like it use to.

  4. The transmission also runs cooler now ๐Ÿ˜Ž

As of this writing I am in the final phase of this process, refining the fuel curve is next.

***Yes, this is on the pricey side of the tuning options, but you can constantly make any adjustments you may ever need and an endless time frame to do it in.

To me it's been worth every penny so far ...... ๐Ÿ˜
