Supercharged 03 Silverado 5.3L
I got the truck last year and instaled kooks headers and y pipe. Corsa catback.
I started playing with auto ve in the fall. But then the transmission failed on me twice. First the 2-4band. And then the 3-4 clutches and the winter with snow and ice came. No a new transmission is on the floor underneath the truck to be mounted tonight or tomorrow.
I also have a E-Force supercharger kit from edelbrock that have started to mount. Basically I'm now at a stock tune. Should I install the 03150003 OS?
Does anyone have a tune file I could use as a base map?
How much should I retard timing compared to the stock tune? Does anyone have data for this injector?
They seem to be replacement parts for the 6.2 liter
