well, you can crack 300 pretty easy with a gte, with a boost controller, better FMIC, lexus afm and 550cc's, down pipe and exhaust, then something like a Apexi SAFC. but that only "fools" the stock computer, so it can provide more or less fuel.
if you want to fully control spark and fuel though, a standalone EMS is a good idea. AEM, maftpro, megasquirt etc. are just a few of the full capability standalone systems.
they are great, but you have to be careful. you can blow up ur motor quick. you can learn how to use them if you are careful, but most times for first time users its best to let a professional at a dyno shop take the controls.
