LS3 Conversion

[moecaballero]

How can I successfully instal a LS3 in my 01 Yukon without having to purchase the ECU and not have to deal with the "drive-by-wire"? Is it even possible?

Thanks!

That will help you a lot more. If you have the money to convert to an ls3, you'll have the money to make it work.
