You could use an AEM wideband failsafe gauge. It allows you to datalog your AFR vs RPM and boost vs RPM. Using this info you can easily adjust your RRFPR to get the majority of your AFR curve in an optimum range. Additionally you'll be able to monitor your AFR while you drive to see if anything goes wrong.

Additionally you could use a VAFC to lower your VTEC point and lean out your sure-to-be-rich top end. That is, unless you want to go the further step and get a better piggyback like a GEMU.

 

Yeah, I have the Novi 1000 with the stock pulley. It does come with the aftercooler, and i have checked for leaks, but i don't see anything.

Will I be able to get that extra HP that i'm down by getting the shop to tune it with the FPR?

 

Only if AFR is the reason why your down on power. Remember though, the FPR is not a very precise way of tuning the car and a EMS would definitely be more beneficial. If your car is running lean and this is why your down on power you could be doing harm to your engine. My fuel pump failed after only a few days after the install and I was running extremely lean and the car seemed down on power. This is very dangerous for your motor

 

what kind of EMS can i use for this ?

 

Stop guessing and GET A WIDEBAND. There is absolutely NOTHING else you can do without it. I wouldn't even dare go into full throttle without knowing any AFR's. Get this, then update the thread. AEM is the easiest in my finding and has a built in free air calibration sensor.

 

I mean you went from Turbo to supercharged??

and Mustangs will always read low..

Plus don't get caught up in numbers.

How does the car feel?

 

If you are running lean the factory ecu will pull ignition timing, resulting in low numbers.

Go back to the dyno and have the rrfpr screw dialed in. Tightening it increase fuel pressure while boosting, while leaving the static pressure alone for part throttle driving.

You want a 11.7 afr while boosting and 14.7afr for part throttle driving. If you place a wideband near the muffler it will read a lower afr...say 0.5 leaner.. so plan accordingly

I had the greddy kit so it was limited.. The car was making more power with the Greddy , but for some reason the car feels faster with the comptech?

 

I will have the tuner go ahead and do that. I appreciate your help....

Hopefully they'll be able to squeeze the HP i'm lacking of safely....

 

This is probably because the SC continues to build boost till redline while the greddy kit runs out of gas early
