About to swap a 6.0 lq4 into my 5.3 surbaban. Looking if anyone can send me a stock 6.0 tune I can put on it.




08 surbaban ltz
5.3 4l60

 

Also looking to do the same thing.

I have an 03 Tahoe with 345k Mike's on it that I love, but the motor is getting tired and has a colossal oil leak I'd rather not spend any money fixing. Was thinking of getting a built LQ4 to swap into it.

 

I am looking into doing the same thing from 5.3 to 6.2l/8sp. What issues would there be? I have the same vehicle, 08 suburban ltz. Have you completed the swap?
