I have been reading a lot of the posts here because I was thinking about installing a DISA manifold as my next modification. But, even with all the information, I was not clear on which manifold would be right for my car (2008 128i). I'm pretty happy with the power my engine makes with the Performance Exhaust and the Performance Intake so I'm not sure I even want to make this mod. My biggest complaint is the stock throttle response. It seems the same pedal action will sometimes produce different responses from the engine, which I find frustrating. Has anyone loaded the Evolve Stage 1 tune on the N52 and what improvements did it make? It seems most go with the Evolve Stage 2 which is the tune for for the N52 with the DISA intake. But I was hoping someone could tell me from personal experience that the Stage 1 tune might be better for me. Thanks.
