get engine management... i use crome, it's free and it only cost me $20 to chip my own ecu... this can give you a free 10+ hp if you tune your powerband to lambda (perfect air:fuel ratio which is 13.7:1)

honda doesnt tune your ecu to run at lambda from the factory to make better gas mileage...

plus engine management will make every bolt-on mod you buy give you more horsepower when you tune your engine... crome makes most bolt on mods and turbos as easy as changing some settings...

when tuning though, data aquisition and a dyno will make your life much easier... try an ostrich realtime emulator... it allows you to hook a laptop to your ecu and collect data... then you can instantly change and upload your new settings to your ecu on the fly while you drive... i have even heard of some software that gathers your data and projects where you could make more horsepower and changes your program.. this is the 'autotune'
