^ but you don't have to worry about boost control in the Tahoe. I still think you would want a laptop in the car when filling up. Would be cool to have the sensor trigger a light or something to tell you it's on tune 1 or 2. Then you could turn your boost according to that as a safe starting point. I thought about using the sensor to go between e98 and e85, but I think I'll just test at the rail as an fittings make life easy and for us we have to drive to get our e85 and use cans and barrels, so everyone's situation is so different.
