I ended up ordering the ST-1M today. Will be cool to compare notes once we get the cams installed.Ended up ordering the Yoshimura ST-2M cam.
I need to get my ECU reflashed again now. I probably need to step up to the aRacer Mini 5 soon, but good grief it is expensive when you add in the AF-1.
I hope I like it. Looks like you don’t really lose much at all on the bottom end and midrange, but gain quite a bit up top.
