Have the Dinan, very happy with it. Added benefit in addition to power: engine ran much smoother at start up and low RPMs. Only real downside is that oil/engine temp runs slightly hotter (maybe 5-10 deg judging by the needle) in high RPM driving in hills. AC being underdriven not noticeable. Also some dealers less likely to deny warranty claims with Dinan (local dealer confirmed this, even if they don't sell Dinan products).
