Trying to find info on an performance pcm for my 99' dakota rt. I was told Mopar performance use to make them but stopped producing them. My question is where or how do I go about locating a performance pcm? Is there an aftermarket company that makes them or do I have to get a performance chip now or what? Also I want to remove the top speed limiter as well. Any info, company names or persons to contact would greatly be appreciated. Thanks in advance fellas.
