Well I found out today that I have an early Rev B bin. Does not work with the EE.XDF for TunerPro couple things off. Looked at PCM number and it's the same for Camaro, Impala etc... for a couple years so I was leary and one guy told me I would have problems with climate control, speedo...

Climate control still works fine. Not sure if my dynaride still works though? I have not heard it turn on since then, maybe it will. Fuel cutoof on Roadmaster was 108 MPH and the Impala SS is 154 MPH, spark tables were identical but fuel tables were richer!

Took it for a 30 minute drive and no error codes. Drives about the same, seemed a little perkier. One thing it did fix was my steering... yup! When I was on the freeway it would jerk a little when I corected, right or left. Now it is smooth. I was thinking more like a PS sensor or PS pump. But the tune made it go away.

So I now have a 1994 Buick RoadMaster Estate Wagon with a Impala SS tune!
