John one last thing, if I do the install will it be drivable to get it to the dealer to have it flashed or will they give me crap about having to instal it themselves and use a bcm from chevy instead of an after market part which I can get for about 1/3 the price, thanks for the help in advance.
I would prep it for removal drive it to the dealer on a sunday or after hours plug it in and tel them it is there for a reprogram its usually a 1 hour labor charge
