Also with out massive mod, turbo, nos or supercharging it what can i do to gain more bhp. Im only after 20-50bhp more.

I have read other topics about this engine. Does seen like a hard one to make faster without a serous mod.

The computer tune does wonders on engines... some more than others. The 5SFE has a farily poor tune from the factory, which richens the top-end fueling as much as 10.1... so leaning that out with some ignition advance can unlock a lot of power. I do agree with lagos on about SAFC tuning not being considered a bolt-on and tweak sort of deal for the novice tuner. It can be very hazardous to your engine... but if you take proper precautions and understand how fueling works with the engine... you should be OK. I'll also say... I wouldn't estimate as high as 10whp on a stock motor... but throw in an intake and exhaust, then you can see 10whp from a tune (on top of gains from the intake and exhaust). The 5SFE or 3SFE for that matter simply aren't agressively performance oriented motors... so tuning is pretty limited. Comparatively speaking... Hondas see upwards of 20whp+ from ECU tuning (on top of basic bolt-ons). 10whp is nothing to sneeze at... but it's not a night/day difference either.
