Just couldn't be bothered I guess. No reason not to.
Thanks for the quick reply, and I think I'll read through that longassthread this PM when I have more time. The chip sounds like a great way to optimize the performance already "lurking" in our cars without going too exotic or complicated, and in the face of these gas prices the added 87 octane code sounds like a genuine bonus! Far as outsmarting the smog nazis, I'm all for that as well.
Would the tactic of swapping the chips back in have to be "relearned" by the car? Looks like I'll be in touch with ECUtune real soon!
