What injectors are yall using for 300+ whp
I think i have an injector problem causing a lean issue and i was wondering what yall were using with the rtek? I have rc's 750/1200's.

the 750's are high impedence "saturated" and the 1200's are low impedence "peak and hold" I have made a harness between the plug and the stock injector resister box to only give the 1200s more resistance.

Ill have to look at the wiring diagram and see if i can get some resistance readings at the ecu. I got flow sheets with the injectors when i bought them. gxl90rx7 are you running this injector driver? How did you fix your problem?

i tried upgrading to 1600's but it was too sketchy staging them
I am now running the same 1000cc injectors with teh haltech and im only hitting 70% duty cycle, same fuel setup. that is why i believe it was caused by the high-imp injector drivers in the stock ecu. the ecu is sending the right p/w length for the duty cycle you want, but it cant supply the current to open a low-imp injector quick enough, so you dont get the same fuel flow as with a low-imp injector driver like the FJO
