Connector is not real snug so added a ziptie to prevent it from working loose

Programmed it with the superchips f5, turned off the limiter and afm used there trans tune. This has the 5.3 so it should do around 136-137 now took it up to 115 to verify but not enough runway to get anymore out of it, the f5 allows tpms adjustment by the way. Also allows you to adjust the throttle response like a pedal commanderView attachment 406969
I went ahead and put the TOW tune in it today, plus the transmission tune. Drove nicely. I might actually start using D instead of manually shifting now.

I purchased a grille from a Suburban LTZ with the intent to make it an RST grille. First pic is how it looked when I bought it. 2nd pic is with it taken apart. The "surround" area will be paint matched Champagne Silver Metallic, and the "inner" area will be gloss black. It was quite a chore to get this thing separated, but I'm anxious for the results!
