I just installed the next gen PIH, and it was well worth the money, the computer was hard to get out, but after its out, its just a matter of moving 11 connector pins and splicing 7 wires adding the BAP sensor and the fan controller and installing the 93 CPU. My kit had the A9M version CPU. the kit really improved the overall perfromance of my car, and I no longer have the check engine light coming on when ever I mash the pedal ( had this problem since I installed the 76 MM C&L Mass Air sensor) even slightly improved gas usage.
