Thanks for the info, kind of what I figured. To answer your question, No, I own a model 98 touring sedan, it's just like all the other 98's untill you sit in the seats and step on the gas and open the supercharger. I bought this car over a '91 420 SEL and a '98 Cadi STS. It will out drive either in the mountain passes between Spokane Wa. and Missoula, MT.
Thanks again, now I guess I need to learn more about programming the PCM.
By-the-way, I learned today that K&N does'nt make a performance filter for this car! Have you gat any feed back on the Fram airHogs?
