I know its time for injectors as I'm running the stock 24lbs. and have approx. 410hp at the flywheel. I've been looking at the SVO 30lb. Injectors but curious what they equate to on an LT1, like 30lbs. exactly or a little more or a little less? Would changing Inectors really be beneficial in terms of performance, any idea on possible gains for me? I plan to run Nitrous in the future but I would like to go with a wet shot so I assume they would be sufficient considering its not a dry shot that requires upgraded injectors. here's my graph, as you can see it breaks up a little bit on the top end and my tuner said that was because of my injectors being maxed out. According to the calculator I am maxed out beyond 100% duty cycle on stock 24's.

 

Looks like valvespring bounce to me. not a static problem. (When they go static they usually flatline on the graph)

 

I was told that before but doesn't seem the case because I shift at 6500rpm with no valve float nothing?

 

Valve float and maxed injectors can feel the same. The car might simply lay over early on the top end. Once your injector D/S hits 100% your engine is starting to run lean and thus loosing power. but that graph looks like floating valves to me too.

At your power level you would be fine with 30lb injectors

What would be the proper sizeing for an LT 383 stroker with Trick Flow Heads and moderatly large cam?
