I drove my friends ext cab 01 4.8 to alabama and towed back my tahoe w/ 5.3 ..towed great, plenty of power, not bad on gas, I cant tell much of a difference between the two..
Yeah I can not either. I also did a K&N and the AirRaid throttle body spacer on mine and it did wonders for the gas milage on it. Plenty of power and acceleration.
