Could it be tuned already??

Out in the Garage the other day working on the Sand Rails. Throats getting a little parched, My buddy and I decided it was Beer:30. My buddy being a previous owner of a 03 7.3 Asked if he could take my truck to the beer store to remember the glory days.

When he returned he stated that it drives awesome like it has a tune on it. I told him it doesn't cause nothing is plugged into the OBDII port. He stated that you don't have to have something plugged in all the time it could be programmed into the computer.

To give you a little background on my truck. I just bought it 2 months ago. All stock that I know of but one thing that caught my eye was that behind where the rear toolbox sits, where it covers the back glass there are two superchips stickers.

My Question is, Is my buddy correct that a vehicle can be programmed with a tune in the computer with no tuner present?

I'm wondering if this guy had a tune on it and left it programmed when He traded it in to the dealership where I purchased it.

If this could be the case is the only way I can find out is by taking it to the dealer?

Re: Could it be tuned already??

you can reflash the stock tune on the pcm to a aftermarket tune without a chip or programmer being plugged in, for example it could just be a 75 hp tow tune flashed to the pcm. done, no programmer or chip. but to me if you got it from a dealer it couldve been reflashed to the stock tune. the dealership should be able to tell you if it has a tune flashed on it

Thanks for your comment, it is possible that the dealer didn't check into it because I basically bought it when the guy turned it in. I was in the right place at the right time! Also it was from a Chrysler dealer so I'm not sure that they have the right tool but who knows. When I have time I will drop it off at the dealer and have them look into it. Would it be bad to run a towing tune when not towing?

Re: Could it be tuned already??

Not going to hurt. With a superchips, it doesnt stay plugged in. You flash /program the tune you want and then remove the programmer.Tune is now in the pcm. That being said, the only way to get that tune off without the programmer is to take it to the dealer and have them reflash the pcm. Also look behind the e-brake at the pcm ans see if anything is plugged into the pcm, or pull it ans see if a chip is installed.

Pull your PCM and see if it has a chip on it. My truck had one on it when I bought it. It was the old style chip that stays on the PCM.

Look down by emergency brake does it have a hole chewed in the side ...
The chip will be there behind duct tape or even still have the wire attached..
Or the pcm could be flashed. ..

I have seen a few trucks with swamps singles and flashed pcms running around.

if you had a superchip in that truck it would smoke like a mofo... even the economy tune will roll some coal

At wide open throttle it will blow black smoke but it is small compared to what I have seen out there!

Would a stock truck blow smoke at all?
