STOCK 5.3 Flex-Fuel Needs More Power
I have a stock 5.3L Flex-Fuel engine in an 07 Silverado ~CLASSIC~ Reg. Cab. It is 4x4 and it has 3.42 gears. It is all stock except a 50 series Flowmaster, single in and out. Im looking for some nice power mods (preferably bolt-on) without going into the engine. It already runs hard which is surprising but Im looking for more. Im not sure what all it has inside stock but its faster than many other similar trucks. Any tips? Like everyone else, Im on a tight budget.
