New numbers

I take it you ended up going with f1 injectors? What size if so? I got some 6.5's awhile back but never really had a chance to see what they would do.
 
Yeah I did and I like them a lot. I'm not sure what size they ended up being but pretty sure they are bigger than that. Truck source talked to Don about the hp I wanted and they decided on something. Whatever they decided on worked lol

Davids are quite a bit more aggressive than a 6.5. Theyre some of the new Apex's Don has been doing. The 6's are a pretty stout injector tho. I ran Flux 6s with a 75 and ran mid 900s on fuel on a 2600us duration tune, and broke into the 9s spraying .060 and .080 jets. They were still very driveable and very little idle haze even without spending a bunch of time tuning the bottom end of the tune.
