This is seriously the best sound I've ever heard coming from an engine! Teh inline six rules all the way... I am very curious WHY you went this way in tuning it. You could have made more power easily by just adding a turbo and intercooler, plus an appropriate head gasket (a thicker one). That would have been very easy, but.... I think I know why you went this way... just one question: how is the throttle response?? Lightning quick I assume?? You gained a significant amount of power this way.

@325iaddict Thank you for the comment! The reason I tuned it the way I did? Because a NA tuned engine have great character, great sound and is really nice to drive. Throttle response is improved by far. In the same time it is easier to get through the yearly vehicle inspection made by the government. That´s why! :)

Thanks for the comment! I will mail you the link to the dyno curve.
