Hello Kevin , First off ,welcome to the forum!I Have pretty much just used Intense and ZZP.I bought my PCM from Intense.The PCM on our Rivs is under the sound dampening panel below the glove box.No need to remove the glove box just a few screws on the lower panel and wa-la, should see the PCM.Todd at Intense helped me alot on this. Good Luck! JIM

Welcome! The Intense PCM was one of my earlier mods as well. A very nice upgrade but you should be interested in a good scanner or even your own tuner...

i forgot to mention i also have a aeroforce interceptor scan guage and a car scanner my family has 3 supercharged cars and we looked into getting a tuner and we figuerd it would be better to just buy the pcms pre tuned

I agree. You should get your own tuner. Best purchase I've made to date.
