Look on the drivers side, in front of and below the battery. Remove plastic cover.

And then...?

Once you remove the plastic cover, carefully remove the two 'rather large' wire harnesses. there is a 6mm bold in the centre of each wire hardness (I think it's a 6mm....if I remember correctly).

Once the wire harnesses are off, the PCM is only held on with a couple of clips at the top.

 

Removing the PCM will only take a couple of minutes.

This is the PCM Valve right? What does it do and how will removing it help performance?

I think your thinking of the PCV valve. This is the PCM, which is the computer that runs the whole truck. They are talking about sending it in to a custom tune shop, and having it tuned for better performance and mpg.

Ok thanx man ..but what would happen if i tryed to start my truck without one instaled...YIKES!!!

Anyway what tune would you recomend i have a few in mind.

I doubt your truck would even start without the PCM.

 

Various places can provide tuning service....wait4me, websters, etc.

I have a wait4me tune and I'm very pleased with it. I opted to get a PCM with the tune so I have the 'factory' PCM in event of any issues (which have been none). Also, no downtime while I was waiting for the tune.

LOL, your truck wont do squat without the PCM installed correctly. The PCM communicates and controlls almost every system on your truck/car, from door chimes to air/fuel mixture.

 

I recommend you do some careful reading before you start modding. At the very least you'll save a few bucks if you plan your mods carefully. Trust me, I've wasted good $$ before I got it right.

Is there anything that has to be done before starting it the first time with a custom tuned PCM, or do just plug in, start it up and go.

PLug it in and start. It may stall the first time or two and may even have a high idle. It'll calm down quickly.

 

You will need to get the 'crank relearn' done as soon as possible, even if it doesn't throw a code. Any decent shop will be able to do this for you and it only takes 5 minutes.

Guess now I need to learn what a crank relearn is! haven't heard of that yet.
