As we all know the 03 being the first year of the Ram Hemi, it is a bit different than the newer models. Basically it doesn't get a lot of love from the aftermarket crowd. But with our uniqueness also comes pride of accomplishment.
So folks feel free to join up and tell us about what all you have done to your 2003 model Ram.

Folks who know Redtruck know's it is my test vehicle which I have tried a few things on, some have failed and some have worked, but the project continues year to year. I believe there is a fix for about every issue that comes up with the right communication.

And with the Moderators approval I hope we can get this thread going.

No approval needed.

If you want me to make you guys a badge, (like the ones under my siggy) just let me know.

Kev i know its alot of work but as clubs grow, it would be cool to see every club having a badge, so ahead of time thank you

Excellent, much appreciated..

I'm thinking this club we won't need individual numbers as we are all "03"..

Here is a confirmation on what needs to be done to change PCM's on a 03. I first was told by pretty much everyone that if you change PCM's you have to reflash the new PCM with your VIN and mileage. Well the day before yesterday I installed a junkyard PCM and it was a simple plug and play. It runs beautifully without any issues. Correct mileage is also indicated. Also loaded the SC3865 without issue. This has been a problem for almost a year with a locked PCM not accepting a factory (dealership) reflash and not loading the tuner. The only thing I could load was a DSP U-7137 and it would throw ABS codes. So the bottom line is that PCM's can be simply swapped out without iissues.

It's been said a over the years that there is basically only one way to raise the idle on a 03 and that is having B&G reflash your PCM. Well actually I have heard of a couple ways folks have supposely done it. I can't say if they work as I haven't actually done any of them but the pwr steering plug method. But anyway I'll mention them to see if anyone wants to experiment or if they have direct knowledge using these methods. 1. inducing a vacum leak by pulling a test cap. 2. Drilling holes in the TB butterfly. 3. Running the AC and finally by pulling the power steering pressure sensor plug. This raises the idle to about 800 rpm's but you need a switch to reconnect the connection when above idle speed while driving or the fuel isn't cut properly and you have over run. A window switch that is activated at 1000 rpm should do the job nicely. I couldn't find a good location to mount the switch as it needs to be accessible to make adjustments while looking at the tach, So I mounted it like this:

This is a dual switch so I still have it available for other uses later on. I'll report more later on.
