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

Before tuning, install a 300 psi pressure gauge on the line tap on the side of the trans case... during tuning keep an eye on the line pressure, at anything more than medium throttle it should reach into the 200-225 psi range.


You have to make sure that the VE and/or MAF tables do not under-report.
