I have a fully built d16z6 with ported d16y8 head zex valvetrain ferra flat valves .020over brian crower stage 3 camshaft aka popcorn cam skunk 2 manifold 320cc injectors bisimoto header (replica) p29 14:1compression eagle crank acl main and rod bearings

Now heres my problem my injectors r maxing out at 8500rpms at 191whp and 131tq im not sure if this is maxing out or is that my max hp that im getting. But the reason i think it maxing out injectors is because it bogs somtimes if u wot in 3rd my friend had this problem with his ls vtec and all he needed was 3"header and 650cc injectors and he didnt bog anynore and he hit 262whp with 176tq....

Anyone have answer for me.. oh its tuned on handata s300 street tuned by my friend

Did you get those numbers off a dyno? Never seen a single cam with N/A numbers this high.
What the duty cycle looking like when it bogs?

 

When it bogs it runs very lean

 

And injectros r at100%

 

Then get bigger injectors and retune.
