Unfortunately I couldn't find anything in his "cabinet" that worked for my setup, but thank you guys for turning me onto Sloppy Mechanics. I've seen a couple videos here and there but for some reason I didn't realize he'd be such an amazing resource for HP Tuners (and tuning in general).

Of course in the past 3 weeks, HP Tuners' tune repository went down due to a website relaunch and now there's no easy way for me to access stock tunes. Fortunately I ran across one in a thread on the HP Tuners forum for a 2005 4.8 manual Silverado and I can use that to compare settings. I made a bunch of changes to my tune to be more in line with that one. I'm hopeful the engine will fire up on that tune and I can use it as a base for a test and tune day at the track next month.

I still need to figure out an inexpensive way to build an exhaust from the downpipes back before that can happen. And before my neighbors call the cops on my engine running with open headers.


There's a seat installed. The shifter feels fine, just a little more lean than I was expecting. I could always get an angled shift lever if it bothers me.
