I double checked with Jerry at Eurocharged and he said that I DON'T need a new tune and I should definitely expect that there is more whp now that the fuel is up to snuff. Once things get a bit warmer around here, I will get a dyno and a/f check to see where we are for a final report on the Needswings/Waldig Crossover tweaked manifolds.
