SAFC Install or Use?

Is the Apex-i Super Air Fuel Controller worth anything in a GSL-SE? I have always wondered but never seen anyone with one installed. I think it could be good for milage and a little tuning for flames...hehe. but i wonder...is the GSL-SE a little too...primitive for it?

GSL-SE uses a 12v signal to the afm, everything else is 0-5v

there is something to be gained with the SAFC, a friend of mine has on his FC. I don't about the FB, but he says that the car runs really rich up top and leaning out the mixture helps power

they work well on an FC because the FC uses the normal 0-5v range, wheres the GSLSE uses the lame 0-12v range.

Basically. But you can go ahead and install the S4 intake system. Then you can let the primary injectors run off the stock ECU and use a Mega squirt for the secondaries.

Replace the stock exhaust with a RB header system. I gained 3 MPG on the freeway.

I am probably going to do mods to get some mpg out of it. Exhaust is a must, there's no emissions in ohio (correct me if i'm wrong Low Impedance)
