My current setup:
CTSC @ 7psi
750cc injectors
AEM EMS

My tuner says with the 750cc injectors I would be able to get rid of the FMU that came with the Comptech Supercharger kit and just tune the AEM EMS with the 750cc injectors. What do you think? And if I was to get rid of the CT FMU what would/should I replace that with?

Any input or suggestions on this topic would be of much help.

750s is huge for 7psi, good thing you have an AEM.. are you upping the boost? but yeah you can ditch the FMU. get a FPR (fuel pressure regulator) , AEM makes a good one.

 

Yes the 7psi is only the beginning

 

OK so you say get rid of the CT FMU and replace it with this... AEM unit?

Just out of curiosity what does it even do differently than what I have now?

thanks

 

dont get rising rate FMU like the one you have. If anything just get an adjustable fuel pressure regulator.

 

So you mean something like this?

and once again... Just out of curiosity what does it even do differently than what I have now?

 

the comptech one raises fuel pressure as boost raises. The one they want you to buy just has an adjustment for fuel pressure but it does not raise the fuel pressure with boost. (The EMS takes care of all that for you by telling the injectors what to do.)

 

And yes that one from AEM will do fine along with the other gazillion ones available on the market.

 

You should be able to use your original FPR that you removed when you installed the Comptech FPR.

Failing that, the AEM is a nice unit that bolts right up to the fuel rail and looks great in red.

 

AHHH! Now it all makes sense. Thanks for the help that is what I will buy
