i guy i worked with said i should get venom fuel injectors(larger fuel injectors)to increase horsepower on the top end(even though i'll run rich at low RPM) is it even worth it? sounds like a waste of gas and money if not needed but never heard of that before

 

no not worth it at all you will run rich all across the board... unless you get a adjustable fuel pressure regulator... and without a wide band you wont be able to tune the new injectors... honestly theres no reason to do it...hell you dont need bigger injectors untill you hit 10psi with a turbo or about 180hp NA..

 

running to rich can even harm your hp...look at slash and his dohc pcm on his sohc

 

Yeah it helped for power but it carboned up fast and so you had to clean it out with a rev otherwise it would be a dog and it sucked always tryin to rev when you needed the power now. I took it off and I have more power on the fly cuz I don't have to clean it out with a rev now, plus I get better gasmileage with the stock computer.

I ran really rich with my Walbro 255lph pump for the turboand I took it off and I'm running stock now. I bought a map clamp and I hooked mylaptop computer up to the OBD-2 Port and my air/fuel ratio was like 3/parts fuel to 10 parts air, and its supposed to be like 1/12 ratio which is what it runs good on now. With the map clamp you can adjust your fuel mixture and so I fine tuned it pretty good with my OBD-2 port scanner program on the laptop.
