I did a search, but it seems to sort by date rather than by relevance

I'm maxed out somewhere, just wondering if it's my in-tank Walbro or the included Radix injectors. I forgot to look at the fuel pressure gauge when I made my last run, but the wideband was getting into the low 12's when it should be in the 10's. The injector duty cycle showed 95% if that matters.

Thanks for any help.

Oh yeah, this is an LQ4 with a mild cam and 2.9" pulley shifting at 5950 if that helps.

 

Hard to say, you need to check the fp, if it is dropping your pump is the weak link.. and if the injectors are maxing idc, could be them..

They should be 43lbs/hr injectors and good for about 480 hp maxed out with no meth. I made 505rwhp on my turbo 4.8 with meth and 11.3 afr spinning it 6200rpm. DC was 106% on the injectors. I know it's a different motor and fi setup, but fuel need should be about the same for the HP.

 

hmm.....i think i may be out of injectors as well. im still running the radix kit injectors. oh well...TVS soon....
