Glad I found this site!

I've been helping my friends building/modifying intake runner lengths on the manifolds but results are varied as the ECU tune is always central to any improvements we do. Thinking this was going to be easy as a OBD cable and software,... what a mistake that was LOL :lol: .

I decided to pick up this challenge with one of the worst possible ECU's to start with, my daily driver is a 2010 VW Golf 2.5, this engine is only sold in North America, so we're gonna have to see how this goes.
