Long time lurker, first post. I’m looking to get a little more grunt out of the engine without breaking the bank. Truck pulls the trailer great but could use a little help when climbing hills. Here is what I’m thinking: air intake, BTR Torque cam, Shorty headers (keep costs down) and a tune. I live in Canada and a set of long tubes and Y-pipes is $2500 plus install, more than I’m wanting to spend. The BTR cam is getting 20ft-lbs more torque at 2500 RPM out of a 5.3L engine and 50+ HP at 5000 RPM, but I’m more interested in the low RPM torque gains. Thoughts/advice?
