A tune and send your ecm out to have it reprogrammed

I did this in my 2009. A local shop that does a lot of LS swaps did my tune and ECM. Love it, and no more AFM/DOD crap to worry about.

 

Did you end up doing the swap? I also have 5.3 motor is going. 160k miles. If u did the swap what issues did u run into if any ?

You can swap in a Gen4 6.0 or 6.2 if you want to go with a bigger engine.
The 2007.5-2009 L76 6.0 (Silverado VortecMax Version) is a direct swap, and has AFM/DOD and VVT.

You can also use the L92, L9H, or L94 6.2L. All Produced 403-Hp/417-Tq.
~2007.5-2009 L92-- VVT, Non FlexFuel, Non AFM/DOD
~2009.5-2013 L9H-- VVT, Flex Fuel, Non AFM/DOD (Same as L92, with the addition of Flex Fuel)
~2010.5-2013 L94-- VVT, Flex Fuel, AFM/DOD (Same as L92 and L9H, with the addition of Flex Fuel and AFM/DOD)

~2007-2013 Cadillac Escalade (L9H for MY 2009, L94 for MY 2010-2013)
~2008-2009 Chevrolet Tahoe (as RPO code L92)
~2007-2013 GMC Yukon Denali/Denali XL (L92 for 2007.5-2010, L94 for MY 2010-2013)
~2007-2013 GMC Sierra Denali (L92 for 2007.5-2010, L9H for MY 2010-2013)
~2008-2009 Hummer H2 (as RPO code L92)
~2009-2013 Chevrolet Silverado 1500 (as RPO code L9H)
~2009-2013 GMC Sierra 1500 (as RPO code L9H)

The 6.2L engines listed, are for the most part drop in.
Any Gen4 5.3L Engine, and the L76 6.0L Truck Engine is plug and play for the most part.
You will need to have the ECU Tuned if going with a larger engine.
Me personally, I would remove any AFM/DOD Hardware from the engine you plan on replacing it with, and use a Non AFM/DOD Cam with the same specs, or a small performance upgrade cam.

I can put L76 6.0 from 07-09 in my 2011 5.3 1500 silverado mostly plug n play besides flash pcm? Also vvt an issue or is that part of the pcm flash

 

Good info. I made this a sticky.

 

Yes plug in play swap and tune

unsure what you mean by vvt an issue, vvt is a mixed decision some say get rid of it and some say keep it. Supposed to help with power down low, great for heavy trucks.

AFM/DOD is the problem child, lifters have the potential to collapse

 

I bought my silverado with dead lifter at 100,000 miles almost on the dot. Instead of an engine swap I pulled the engine did a Cam, valve springs, ported heads (I hand ported and measured them #243 heads), ARP studs, new oil pump, timing chains, and exhuast. I check the tolerenes on the cam bearings to make sure they were on and i also checkd the rod bearings. I picked up about 80 Hp and i have had it for 6 years and it hasnt missed a lick. I also drive it VERY hard. put it this way i have a set of tries that were rated for 45,000 miles and they are cooked at 12k.... The 5.3 are great engines when you get rid of the AFM/DOD systems. I will hopefully turbo it down the road if the budget allows.

 

03 did a 5.3 to 6.0 with 4l80 swap I put headers straight pipe and had to get the computer programmed but it lacks power if I press the pedal it will slowly go idk what can be wrong with it but just can’t find the problem

 

what did you get the 6.0 out of?

 

Out of a 06 2500 Silverado it’s flex fuel

 

flex fuel..?Pretty sure only the 5.3 is flex fuel from factory unless the vortec maxx is flex fuel, but that would be a premium gas LQ9

Possibly a CNG engine?
damnit just realized this is an old post, not sure why i clicked it . damnit

 

Possibly drive by wire hesitation/lag, that is normal without some intervention that we probably aren't supposed to do unfortunately.
