I also have an early '99 that I am thinking about getting a chip for. From all the reading I have done, people are suggesting that we should upgrade our PCM from the XLE to the PMT-1 because of the improvment in shifting. I am assuming this is for people with automatic transmissions. Is this still recommended or even needed for people that have a 6-speed? Does upgrading do anything else for you besides improve the shifting on the auto transmission? Will the F5 chip work with the XLE PCM? If it does, is it worth me spending the money on a PMT-1 PCM even though I have a 6-speed?
