I have nearly 80000 kms on my 4.3 and so far my only complaint was towing a 4000 lbs camper with some stuff in the back of the truck. The issue was not being able to keep it in 6th gear so I had to run at 105 km/h @ 2800 rpm in 5th. Would like to know how the 5.3 would fare with that extra HP. Other than its been good.

Just curious how much modification was required for the MIT to fit and wether it made a difference or not.
