Review on 🚀 Enhanced Performance: Comp Cams K54-412-11 XFI RPM 212/218 Hydraulic Roller Cam K-Kit for GM LS GEN III/IV by Terrance Duncan

A performance boost you'll really feel in your seat. Some reviewers state that it works great without a melody. Maybe yes, but tune in anyway! You will have MUCH better results! I had the Black Bear on and it pulled noticeably harder than without the tune. I've been using this camera for a year now and I'm still getting a real 14-15 mpg on regular gas, 33" tires and 3:73 gears, same as the stock version but now with a lot more punch. in your pants! This cam has a slight idle tilt and sounds great. I highly recommend a good exhaust setup and a good cold air intake setup, not one of those K&N bitches everyone buys that sucks hot air out from under the hood, but a real cold air intake like the stock version without the maze of tubes the air has to go through . The LS engine LOVES air and this cam will fill that need for more air. Don't listen to the self-proclaimed camera experts who call it "kids camera". This is a great upgrade for your Silverado/Sierra pickup and makes it a great everyday driver!
