I can't repair pcms. www.solopcms.com is a good place I've seen for new ones though.
Normally I'd say my SCT tunes are AWESOME on stock trucks. But you'll have to hang on a little bit longer. SCT has discontinued the x2 9550 model before they've finished putting the Dodge platform on their X3 device. They will have the X3 device out end of summer. Supposedly it will have a data logger. Please email SCT WEEKLY via www.sctflash.com contact info and ask about their X3 Dodge device so they continue to see the demand. With as many folks as I am sending to them to email about this, they seem to be responding.
