When I went from my 5.3 Silverado to my wife's 6.2 Tahoe I was so impressed. The power was there but with a little self control you could get mid 20s MPG on the highway.
I traded my 5.3 Silverado for a Ram TRX. HOLY ******. First time I did 0-60 I actually let off the gas early. I had an even bigger oh ****** moment the other day when I got gas for it. 33 gallon tank of premium and I get 9-11 MPG. Its a thrilling ride on the streets and at the gas pump. My 5.3 was only getting 13 MPG thanks to the tires and my desired to hear the exhaust. But at least it was 87 octane. I have started taking my wife's Tahoe when I need to run out. Feels good to get behind that wheel again and not as painful at the pump.
Perhaps I should have waited for the refreshed Silverado.
