HP Tuners now supports JTEC PCMs
Yes, JTEC controllers are worth it in the right applications. Fully tuneable with SCT software and I think with Sykes ECU tuning as well, even for rowdy cams and moderate supercharged applications. In a serious application you'd need an aftermarket crank trigger wheel to get rid of the flex plate setup, but for most street applications that flex plate trigger wheel is fine too.
