hey all you car tech-guys, i know that it's possible to get regrind cams for our engines but what will they actually do for our performace? I have a GT, is there a way that i can get some regrinds that will make my engine better than GTS? or titanium ones? what about pistons will i have to change those to and get higher compression pistons? what would be the gains if i got high compression pistons to match the GTS and better cams. thanks in advanced
