Do you happen to know the factory upshift / downshift MPH and the MPH vs TP parameters for a C5 with the 3.15:1 differential? Thanks for any help. I have a predator programmer to make the changes.
You can get all the LS tune files in EFILIVE format from this website-----If you don't have EFILIVE you can download their free demo program off their website to open the files
On a C5 the engine and trans tuning is all on one computer--So just find the year of your car and whether it's a manual or auto trans and you'll be able to see ALL the upshift / downshift points both at WOT and P/T http://tunefiledepot.com
Didn't say you could make adjustments to shift points with the EFILIVE tune files-- The poster said all he wanted to see were the STOCK shift points so he can use that info to see what it's programmed as STOCK
info please
