I just bought one and had a few questions. Is it a good setup? Does it have a turbo timer on it? What levels are good for towing? What levels are safe for stock auto tranny? Does it smoke? Are you happy with it? Its going on a 03 QC dually with a SO motor and auto tranny. I have a AFE stage 2 with the pro guard 7, MBRP 4" turbo back with a 5" tip, I have gauges already. If it doesnt come with a turbo timer, what is a good brand to buy? Thanks
