vtech controller???

i have a automatic 2003 civic ex, would a vtech controller help any with my performance, and if so how???

a vtec (no H) controller won't do anything unless you upgrade your motor with a cam or something along those lines.

get an a/f (air to fuel) ratio gauge as well...

A manual transmission would probably help more, but on a bog standard Econobox with VTEC, it wouldn't do anything.
