Shift Points on 4.8
What is everyone's shift points on a 4.8 Silverado. Mine is not programmed and it rev's out of first at 52 mph, and rev's out of second at 92 mph. It dies from 52-62, but pulls from 62 mph - 92 mph. I have a 2006 Crew Cab with Electric Fans.. Any suggestions on horsepower gains for cheap prices ?

Re: Shift Points on 4.8
check the sticky thread out at the top of the forum
if not, call a custom tuner aka Nelson and ask him.

Re: Shift Points on 4.8
I tuned my 1-2 shift for 5800 RPM and my 2-3 shift at 5600 RPM. This is on a 5.3.
