Try speedtuningusa website. I've heard about them but haven't tried out. It costs like $350 for ECU upgrade.

yes they have them 20 hp for 325 , anybody use them,is it wise to have the ecu flashed ?

pretty much all perf upgrades involve ECU upgrade anyway ... the 20hps extra is for the high end ratio only so if you don't 'redline' your car, you don't need it.

does the reprogram make it so you get full throttle right away ?
