Okay, so lets start off with the mod list:

-K&N cone filter intake
-TB mod
-TB port
-Wired Open 5th/6th ports

-Old skewl HKS catback
-Gutted Cats
-Picking up the Header Tomarrow


Alright first off, is it possible to pick up the low end since i wired opend up my 5/6 ports and removed my 2nd butterfly's on my TB (i regained plenty of power up above but i know i lost it down below). I really wanna get some more power in the car and i know these things run pig rich to begin with so i wanna retune it with something like an old APEXi AFC unit or something and possibly tune it with the narrowband. Is there some HP that can be picked up by doing this? can i get some of my low end back? any help would be appreciated

 

I'd say make your 5th/6th ports work correctly.
The SAFC is a good idea but dont tune it with a narrowband!

 

if anything get an SAFC on ebay for like $300 and wideband for a little more go to a tuner local around you that works on rotarys i got a guy around me who charges $100 an hour and he provides the wideband aand once you do that it should all be good and what kouki said get your 5th/6th ports to work
