i have a comptech sc on the way after being on b/o for 6 weeks. in that time i was researching everyons problems with the kit but never found out if the kit is tuneable with what comptech gives you. do you have to buy anadd on ems like an AEM? thanx for any help

 

you can use the FPR but it just changes the whole power band. I bought a NEO AFC. As I stillw ant to pass emissions Im not doing the EMS AMS E manage etc route.
