If Kenny and Pete at Advan give it the tick of approval its the real deal. Peter's been building tough street and race cars for years, primarily GTRs. He literally spends every day either on the dyno or in the engine room building. Kenny's been around FI BMWs and most of the Sydney workshops for the best part of a decade. Knowing him personally, he's fastidious, he wouldn't have gone with it if it wasn't the best available option on the market to achieve his goals.
Powerchip is a totally different kettle of fish, you really can't compare the two, procede from what I have seen (which is limited) is tunable, powerchip is a one size fits all.
