WOW that got serious real quick. Here are the things i have learned along the way. Single turbo cars still need TWO waste gates. Think about it. Each bank gets a wastegate on a twin setup. Since you put a single turbo on it there are still two banks of exhaust moving air. You need to add another waste gate for the drivers side header. The closer to the collector the better because the exhaust is at its hottest and its more compact and a given hole with flow more air with more temp. Secondly, without knowing what boost and where you AFRs are you should never do a full pull. The burned up pistons are from prolonged full throttle under boost. This was an expensive lesson in comparison to a dyno session where you can control what goes on and for how long.
