OK I've just asked this question in another thread but i think its worthy of its own. I just ran a 15.2 at the track with my 86 N/A, I'm happy with this time but think that in order for me to go any faster i'm goin to need to tune it, With a lightly modded N/A s4 do i really need something like a microtech that i can adjust ignition with or will i notice a gain if i just use an s-afc II and have it tuned at a dyno?

 

If you don't have a fuel computer - get one.
Gains on the non-turbos are significant, as your're already running too rich.
Other mods would include flywheel, CDI box if you've done all the intake/exhaust stuff.

Will this CDI box do more for me than an S-AFC II? I can really only afford one of the two right now

 

Go with the fuel computer first - it'll give you better gains and save you gas!

The CDI and flywheel is some of the last mods you can do for the non-turbo 13B before digging into the engine itself.
