$1350 shipped for the ecu only. I don’t have any extra sensors but you can pick up a GM IAT and GM 3 bar map sensor for about $100. The ecus alone new right now are $1900.oh I'm deff having someone else tune it. Even if i go with chrome ill not be doing it. Some things im okay with having someone else do, and tuning is one of them lol. How much would you be talking for aem v2? all sensors ect included? I have to ask, what is the difference between the 99 flashable ecu vs chrome?
