I just want some other opinions. A customer brought me a truck this evening.
Truck 04 Silverado
4.8 magnacharger. custom cam. 56 lbs injectors, meth inj, full bolt ons.
The truck surged wouldn't idle. flat and lazy.
I strapped it on the dyno.
When I downloaded the file I knew I was in trouble. Monday Im going to flash the latest OS on tisweb.
The sad thing is the place that tuned this truck is a huge shop. They charged him 600.00 for the tune. I have no idea how they scaled the maf.
Look at his shift points and rev limiter. I wonder why it was bouncing off the limiter between shifts
