However believe it OR not Mike is trying to build a performance header a full EL design aimed at MAX power however he is also trying to refine his UEL design to yield respectable numbers.
Below is the 2.0i UEL over stock 4hp meh but at least a basis. We all understand how F'd up that stock 2.0i manifold is so getting result from the most twisted UEL is almost automatice. Also 1stick3pedals
has UEL on his boosted 09 2.5i he lost HP over the stock and has it documented.
As more folks install and tune around the header we hope to build larger db of dyno result (to compare what mods, type of tune and final hp numbers)
