Stock 4.3 with turbo kit not wanting to upgrade to marine manifold because I don?t want too much money invested in this build it?s all eBay turbo parts hot side was fabricated by myself wanting to do a maf tune because I don?t have speed density os options. I need some tips or some tunes to get me started because I don?t know what the hell im doing? and any other tunes I can do to get more hp out of this truck
HP will be limited to fuel flow.
Do you have a wideband?
Also its hard to help without seeing your tune.
here is the stock tune and no wideband at the moment
Major bummer that it's a vortec computer and not a P01 controller, so much more you can do with the newer computer.
What are you doing for fueling?
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Stock injectors installing a quantum fuel pump would have to change intake for new injectors and not doing that right now so I need to tune my maf instead of speed density what’s the best route
Should install larger injectors. You could run out of injector with very little boost. Aus injection sells bigger injectors for the vortec 4.3 stock manifolds.
