I have had this truck for a year or two and decided to put a cam and turbo it and I got it to idle, but doesn't want to start very good. And when I give it some gas it doesn't want to accelerate and it makes a pretty loud hissing sound. I have checked for vacuum leaks, still using the stock dbw throttle body. I put the stock 1 bar map sensor back in it for now and the stock values to try to rule out the map sensor. I have tuned different vehicles before, but they have all been dbc throttle bodies. Can anyone tell what is going on with it? thanks
