I think I might be maxing them out. C4 car with a vortech and 50lbs injectors. Car pulls hard to about 6400 then starts cutting out (acts like a rev limiter)wideband shows lean. I have a 255 forced induction with a 310 external and a KB boost-a-pump -6an feed and a -4an return. I have taken back to the tuner had the chip reflashed rev moved to 10,000rpms. Last week swap out valve springs thinking valve float. Fuel preasure holds steady. Any Ideas??????????

This car was a Glide with two kits.One on 150 one on 100. with 42# Injectors.
You really need a -8 feed and a -6 return on your car

I had a car do the same thing once.
It had 2 BAD Injectors. Did you buy those injectors new? Have you had them checked or flowed lately

I was thinking bigger feed too. Pressure is only part of the story....flow is the other.

This is the second set of new injectors in the last year. Was thinking I'm running out of volumn. I have heard of several 650hp + but they were on spary with either a seprate fuel system or tapped into the fuel line meaning the fuel rail did not what supply "all the power" I"m sure both of those kits had their own fuel supply. Is there anywhere near that flow test them? That would make sense having a bad injector.

Correct. Not only that but you have a tiny return with that -4. If it was me I would swap it to a -10 feed and a -6 return.
