Hey Guys!

If I took the blower off of my car (selling the car) and am using an EfiLive COS3 OS in it, would I have to ask the dealer to reflash my stock OS in to load up my OEM OS non blower tune in?

Please tell me what I'd have to do.

Thanks in advance!

You can leave that OS in there if you want just get it retuned or whoever tuned it can just load your stock on back in.

Thanks for your help!

I'm a bit dense, so you mean that I don't have to have the dealer reflash my pcm to over write the COS3 Efilive setup that's in there now?

I could just put my 1 BAR MAP sensor in and reflash it with the tune prior to the upgrade?

Like I said, I'm a bit dense!
