I have a 5.3 with the 6L80 in it and was hoping to swap over to a 6.2 but i can’t find much online about what i will need to replace, anything would help. I know i’ll need a new ECM and possibly a new flex plate but besides that i’m not sure. Thanks in advance!
I have a 2014 silverado v8 5.3 leveled on 35's with a tune on it, true dual straight pipes with cats, and I get around 17-18 highway cruising about 70 mph, and around 12-15 city depending on how much i put my foot on it and feel like speeding or hearing my exhaust.
