it's a second gen, ill try to add some tonight. Would that be my biggest gains? Im looking for more power. I just bought 30 lb injectors, and a fuel pressure regulator that should solve any fuel issues. I also have a built 4l60e.

I know nothing about FPR's but from dyno's that I have personally seen from GMHTP articles where they tested many mods one by one and showed previous power and new power, and from the list you've shown those two jump out at me. Not huge gains, but anywhere from 8-15hp would be expected I'd think... Also, did you get 1.6 roller rockers? Those are like 7hp over 1.5's if they work with your geometry. EDIT, I see you listed your cam being for 1.6 so I'd imagine you got 1.6's already.

Also, according to solomon's site, when you changed the cam you should have gotten a power tune not just the basic tune.

Its a power tune, its just the first one he sent me. I know I need injectors, but then I have to get it re-tuned. I think ill throw them on sometime soon and then get a dyno tune.
