'99 Silverado 5.3, 221/229 camshaft, mild stall converter, built 4l60e, part #12609749 injector ( I believe i have the right injector data, if not correct please let me know).
Has a bit of a issue cold starting and hot starting. I am unsure on the injector data as i got a few different results and thought possibly this was my issue. Other then starting the truck runs and drives great.
Here is the latest tune i've done. Any help is appreciated!
