have read a lot of positive comments about John Copes converters so while looking at the Cope racing site I noticed an Icon for PTC. That led me to a spec sheet that you fill out for a quote on a converter. So why is the PTC spec sheet on the Cope site? Does PTC build converters for Cope? Also, anyone have experience with SMR converters? The marketing info reads very good but I would like to read some actual user responses before I make a purchase.
