If you dont mind me asking, what is your S-AFC 2 and AVC-R set at. Im trying to figure out the best settings for mine. I currently have a K&N cone filter, Walboro 255 fuel pump, Apexi bov, 3in down pipe, 3in test pipe, and Dual N1 exhaust. Thanx

AFC will need to be tuned with a wideband and Dec-Air will need to be set up to your car as well. There are directions to set up Dec-Air correctly in the manual.

AVCR is simple, just set the boost to what you want to boost at and boost away.

i know how to set up the boost but the duty is what im mainly concerned about. I didnt know if there was a good percentage to set it at.

So there's no way i can tune any of it myself . Is there any way i can change any settings on it because i was trying to figure it out (dont have manual) and i didnt kno if i messed something up.

You can tune the SAFC if you go buy a Wideband O2 sensor, otherwise you have no clue if you are running rich or lean. I have a PLX devices Wideband O2 sensor on my car and it comes in handy to tune the thing. If you dont have the instruction manual, go to Apexi's website and download it. they have both the wiring diagrams and the instruction manual. If you follow the directions,setting up the decl air is really easy and you dont need a wideband or anything to do that.

As a side note, from my experience with SRs that have their boost raised, they tend to run a bit too rich in the low to mid RPMs so you get a bit better response and power if you lean it out a bit between 2500-4000rpm
