Just set my valve lash today and was checking out the info on the site. I drive a 2005 with z1 head/stock cams valve train up top a jdm k24a. I've been running my stock prb ECU for years. I thought inspected my spark plus and of course I'm running lean, but the motor runs like a top and has for four years daily driving. Not sure there is anyone else as brave, stupid, or cheap as me running a frank w/o kpro, but hey it rips and drives well. I want to race a k20 rsx-s with kpro against my unturned frank to see the out come. Would I get pulled on?
