Ive had this truck since july and these are the mods that I have done so far. I gotta say the truck drives even better with these rims and tires and the fuel economy got better as I am getting 16mpg in the city and 20mpg on the highway going at like 130 to 140km/h. (. the only downside is that the speedometer is of by 10km/h and I wont get a tune for it as I am waiting for the new version of pulsar to be released. the only two issues i had so far with the truck is the paint chipping on the hood, and some rattling noises that are from the back seat ( i took it to the dealer and they said they fixed it as it was an unlubricated part but that was not the issue so I will be taking it to a friends garage since he has years of experience with gm trucks and he does a better job than the factory itself honestly.)
