Default Upgraded injectors over 350RWHP?

I have posted this on other boards and have pretty much made up my mind but I thought I would ask. I am putting down the numbers in my sig and have recently developed a 5500-6100 miss. Entire ignition is new and getting good fuel pressure at the shrader valve. Most are saying that I am way over duty cycle for the stock injectors. What injectors are you guys running in your cars over 350rear wheel?

SVO 30-36lb should be more than enough for what your doing. Goos power your getting out that setup by the way.

I have the same problem. When it gets hot, it sputters past 5500rpm. I am trying to figure it out. I have the Heads and Intake port-matched.

Thanks I think my good power is due to my heads. They flow really well. So do you think I am definitely making too much power for the stock ones(24.9#)?

I made 398 rwhp and 372 rwtq with my stock injectors and fuel system!

On the last round of mods...
Mcleod Street Twin clutch with steel flywheel
KooK's Stainless Steel 1-7/8" headers
Racetronix fuel pump with harness
Racetronix 42# injectors

Dyno results after were, 401 rwhp and 375 rwtq. The motor idles smoother with the larger injectors than it ever did with the stockers, and the 42# injectors should be good up until 500 rwhp... if I ever want to go big!

My opinion.... go with the Racetronix 42# injectors and never worry again!
