That's definitely good to know... the argument from TVT seemed very convincing but I don't know if there was ever actual data to back up those claims..[/QUOTE]

Yes I have the TVT injectors, car runs just fine. I see where some people have said we need larger injectors if we add more horsepower and on the other hand I see where Kleemann , that supercharged the 3.2 motor, used the same injectors.
When I use the Google calculator for injectors, I see we need larger injectors for more H.P.. Take this as a little information as it does not answer your question or mine.
