dfi

Make sure you post where you got your injectors serviced...others may need the same help. And welcome to KZRider.

rc fuel injection in cali does them 35 each for clean test and 94 each for brand new ones.. i figured out two issues in one stone fuel pump was weak and the regulator is no good since its only doing 30 psi when i try to adjust it the gauge drops it like 25 psi.. should be 33 at idle and 36 at full throttle so i have read...now the question is will that 3 to 6 lb cause the stumble at 1/4 to about 1/2 throttle 

I suspect it’s injector related but fuel pressure is also critical 

well i guess am gonna be going threw one thing at a time so nothing is missed or overlooked.. troubleshooting sucks but its how we learn i guess me i would have did the carb swap but my bf says to keep the dfi he has a red one thats carbs it was already swapped when we got it.. any through on swapping to carbs.. or keep the dfi

I sent my injectors out to rc injectors from my turbo through charlie at evergreen turbos  who is an rc dealer. They came back like brand new. It was defiantly worth the money. They came back with a flo chart showing before and after. 

thats good to know... am gonna do some more tinkering with the fuel regulator see how it runs,,,then ill send out the injectors as thats the last thing to be serviced in the dfi system everything else has been double checked,,, i have two of every sensor and the ecu box ohm everything out changed everything back and fourth found the two fuel pumps both factory are weak i got a new one in there now but the regulator wont go over 30 psi,,,so its that and the injectors left then the whole system has been checked the wiring is ok nothing is green or anything threw out the wiring anything else should i check or do?? 

The guys on the turbo site are using these walbro pumps .
