A Ford lightning MAF will work but you need to rewire the connector to the Nissan harness. Greddy E-Manage, although DEFFINETELY not one of my favorite managements (still a piggyback) will be able to correct the A/F settings that will be changed by the larger MAF (will run leaner). I belive stock MAFS will max out somewhere in the near of 400hp but im not positive. GL
