I am currently running stock injectors and I am noticing many people making more power than me with smaller cams and older engines. The only difference being is that I am on stock injectors while they are on larger ones. My modifications are as Follows:

Rebuilt/Blue Printed/Balanced 2000yr Bottom End
Livernois Motorsports Stage 2 Heads with 2.02 intake valves 220c intake port
Heads milled to 60cc 10.9:1 Compression
236/ 236 .602/.602 LSA 113 Cam
Vararam Intake
LS6 Intake Manifold
Ported Throttle Body
Kooks 1 7/8 Headers
Off Road X-Pipe
B & B cat-back
Dyno-tuned 434/390 rwhp/tq
Redline 7000 rpm

So, do you think I would benefit from upgrading the injectors? Thanks.

Did you tuner say they were holding you back? That's very close to the limits of those injectors, so I wouldn't be surprised if they were, but the tuner should have told you. A FAST intake would probably help you a lot as well seeing as you're spinning to 7000RPMs..

My stock injectors (26#'s) were maxed out when I was running cam only. I added heads and went to 28#'s and I maxed out there as well. Went with SVO 30#'s just recently and now my duty cycle is in the 60's. We're pretty close in numbers also.

I would definetely upgrade to a minimum of 30#'s.

42#ers if u have more mods planned. these seem to be the all around injectors, as they support some good power too. I'm at 64% on my 5psi setup..
