Thanks for the info! Went with the Equus Model 3100, and as BOOSTED SNAKE did, I called Summit Racing ($125.39, what a price, CHECKER wanted $295 locally)...Summit told me the unit was back ordered and they would be available around the first of August, however, they were able to drop ship it (overnight) from the manufacturer for a few extra bucks! I will use it for the rest of the summer. The list of winter mods is long and distinguished, so come spring I will pick up some Ease Diagnostic gear to use on the dyno, and ebay the EQU-3100...thanks again!
