5.3 flex fuel with super chip and magnaflow muffler... Used to pull it with my ltz 1500 with 5.3 stock same shit pulls it like a champ the way magic sets the trailer up the axles are way far back so there not crazy amount of tongue weight... To tell u the 100% truth I rather put the boat in the water with my Tahoe I had a nnbs hd d max and it was a pain to pull the boat out cuz it would just burn the tires slipping the hoe just pulls it out like its it's job!

No rubbing the back bottoms out I still got my norcallss tb springs and cut off bumps top brackets to install it will be way better after I install that but the boat stays out at the lake and I don't tow it very far so it's no big deal not like I'm going on road trips with it
