Default Not true....plus one spin around the block and they'll know.....

....best to have a spare ECU with a chip in it. Swap ECU's prior to service and reset the power-loss DTC.

Default a dealer friend of mine said that even if u change ECU's

they can tell, that there are other places to save info. He told me how they can tell if your chipped, pulled the engine, max rpm, max speed etc...

Default WE DON'T KNOW FOR SURE

But likely there are things we don't know about.

Remember, people can talk out of their *** and how can you tell if they're positive or not?

Here's the thing -- DO NOT assume they can't find out anything, given enough digging. If you want no troubles, stay stock. Anything else is a "hedge."

Default Mechanic at my dealer told me they have no way to know...unless the drive it/look at ECU.

He said there is no way to tell via their computer.
