HP Tuners Tutorials - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Gregski** · 08-22-2019, 02:58 AM

with your permission I would like to post some HP Tuners Tutorials for absolute beginners while this stuff is fresh in my mind following my swap. (2001 GMC Sierra donor 4.8L / 4L60e into a 1974 GMC / C10 2WD aka "Rusty...lives")

I have originally posted these on the LS Swapped Square Body GM Trucks ('73-'86 C/K & '87-'91 R/V) Facebook Group receiving positive feedback and a suggestion was made that unfortunately it is difficult to find all prior older posts there and that I may want to find an alternative home for these resources.

so hope you don't mind, feedback and corrections welcomed, may take me a while to reformat them to fit this forum format
