[QUOTE="prozac, post: 701698, member: 1726"] Problem with a MAP system such as Siemens is that out-of-box it is not very adaptable to mods which let the engine breathe better. It's best to couple it up with a piggyback or standalone. I believe Matspeed is working on some electronics to alleviate this. From stock-to-stock comparisons between the 4G93P MAF and MAP system, the latter tends to run leaner at high rpms. But this is still debatable on a car to car basis. [/QUOTE]
