allison park, 

Was looking for best advice on the 944s2 dme plug-in plug-out (EPROM) chips. Recently I installed the Racing Pros 944s2 chip on my 1989 944s2 and kept the stock chip. They claim 10-12% power increase. I did notice my 944s2 polls a bit harder at all ranges, and more at high end. The car was very strong before the chip change, but now hits 150mph with no issues.
