Q. about programmers/chips - how to get back to stock
Bear with me guys, because these questions are kind of elementary:
I have a 96 PSD w/5spd. I've suspected that it was chipped or programmed, ever since I bought it a few years ago, because low end seems sluggish but top end seems over the top. Now, I realize that the turbo takes time to spool, etc, but this one seems a little too long of a wait on the bottom end, and then once it spools the thing launches.
I haven't checked the PCM to see if it's chipped, but I'm going to soon. If it is, and I simply remove the chip, will that return it to stock?
If it's programmed (I don't have the programmer), it's my understanding that a dealer has to "reflash" the PCM to get it back to stock? Is that correct? If I don't see a chip, how will I know it's programmed? Can a dealer recognize it's been programmed simply buy plugging in a diagnostic tool? I'm curious about that. Also, if it is indeed programmed, does anyone have a rough idea of what it costs to "reflash" the computer? I've heard it's kind of spendy...
One last thing - if it is indeed programmed, could I skip the dealer crap and simply buy another programmer and use it? Would it just reprogram the computer to the programmer's parameters? Or would it not work right because it would need to recognize a base line (stock), which wouldn't be there if it was already currently programmed? Or could I simply reprogram with another programmer, with the only downfall being that, even if I told the new programmer to save the stock setting, it would indeed recognize the currently modified setting and save it as "stock"?
I hope that last paragraph makes sense to some. It's hard to say what I'm trying to ask! Any advice would be appreciated. I've owned many diesels but have not messed with chips or programmers.
This all stems from two things:
1) I'm not that happy with the current performance curve
2) I'm interested in buying programmer, but need to know if I have to jump through a few hoops prior to being able to use it (due to the truck possibly already being programmed).
