i just bought an 06 mega cab with g56 and was wanting to put my crazy larry on it, but i dont want to void any warranty. is it possible to buy an ecm out of a wrecked truck and put in mine while i have the programmer on it and switch it back to the original if i have to have my truck worked on at the dealership. is this possible? how hard would they be to switch? any advice is greatly appreciated.

 

i think it would be very possible.

 

how would the whole chipped key thing work though?
