Pcm

can you buy another pcm and swap it out for a tuned pcm and keep the original if you need any warranty work done ect is this a possible thing to do or is that just overkill?

There are a number of hand-held tuners that let you swap tunes (including the factory tune) in and out at will. The Diablo inTune comes to mind.

Seems like that would be a better solution than swapping PCMs.

If you are going to void your warranty, you take the risk. Do not try and be dishonest. That is my recommendation.

If you purchase a new PCM and have it setup for your car you can swap them back and forth.

Some other folks have suggested that other computers in the car that "talk" to the ECM, might store or transfer some information that could give you away.

No personal experience here.

It's also the ONLY way to get CoW BOOSTER! installed.... Without me being there.

Call any time.
