Alright, I just got this in the mail today, but I am somehow not finding where my PCM is. The Bonneville is not on the list of cars for where they are that they sent me. If someone could PLEASE help me that would be great. Thanks in advance

Remove the hush panel above your RF passenger'* feet. The PCM is underneath the glovebox, silver in color, with four connectors going to it. It'* a little finicky coming out. After you get it out, remove the 2 small screws on the PROM access door. Your jet plugs into the PCM, and your stock PROM plugs into the Jet piggy-back style.

Alright, thanks Willwren, do you think it will take more than 30 minutes?

Plan on an hour. It can be tough just figuring out how to put it back in. Run your seat all the way down and back, and plan on working upside down, laying in the footwell. It can be tough, but at least it'* INSIDE the car instead of out in the elements!

Alright, thanks a lot, Ill get right to it.

Ya, man it is a pain in the ***. I will just have to really finick with it once more to get it out. Be back in a while.

Is there a break in period? Is it effective right away?
I just finished. I took it for a ride, it feels like a little more power, not quite what i was expecting though. I thought the shifts would be notably different yet they seem every bit the same. What do you think?
