    I'm guessing your talking about a re-map. You should only remap after you've done other performance mods (exhaust, filter, manifolds), all a re-map does is release those few extra horses that the orginal ECU map was holding back. If your lucky you'll probably get about 8-9hp gain although from what i've heard torque figures do benefit a lot, all depends really.

    not really worth it on a small normally aspirated engine, might get 5-10 bhp from one

    Yeah not really worth it Stephen, just do the air box mods and cat back exhaust if you've not already.
