Hey. After doing extensive reading on here including parts of the vortech thread I decided to go with RC 650cc injectors, a utec and a return fuel system on top of my previous exhaust and intake mods. My problems now are the following
A) after installing the vortech and fuel system it will no longer rev past 2500 with or without a load. It would rev jus fine with the utec before installing the fuel or sc kit
B) it runs so rich I can't correct it out with the utec even adjusted to -99.9 in the fuel maps. My Aem gauge is pinned at 10 and the utec logger reads continuously rich.

650cc injectors seem to be what was recommended with this set up and a utec so what am I missing?

 

Are the RC injectors low impedance? or high impedance.

 

Did you unplug your MAF by chance? That will also effect the limit to where you can rev...

You have a RFS you mentioned also, if the impedance is correct, what did you set your base pressure to on your regulator?

 

Solved the rich problem. Reset the ecu again and it started to idle without being rich at a correction of -10. I then realized the fuel pressure was set at 32 and it has since been increased to about 50. I am tuning now but haven't checked the rpm to see if it is still limited.
I unplugged the maf for the install but it is plugged back in. The injectors should be the correct impedance as I got them from another board member.

 

Thanks for the help. All is working now after a few ecu resets.

 

Awesome man, always love DIY work... Enjoy!
