I done some minor mods to my s4 na like fully rebuilt s5 streetport na with turbo 2 housings, full rb exhuast, air intake, and stock ecu. I was reading around and seen the jacob's ignition
was wondering if anyone has used the jacob's rotary fc1000 and if they recommend it...

Im looking to get the most power out my s4na without turbo charging or major stuff like that while retanning my stock ecu.

 

I bought one a few months ago for my my 91' Turbo. Unfortunately I haven't installed it yet. I'd like to know what poeple think as well.
