I want to see what this gains with a mace cam. This is increasing the velocity to the heads and cylinders and is supposed to be massive.

Filling the big extra gaps and hallways with plastic and then smoothing the remaining pathways to the cylinders. There is a guy in Washington state (I think) who is taking the Colorado Lgz intake manifold, opening it up. On the 5.3, 6.2 and the camaro version of our motor (different intake manifold and different down pipes) all make gains from intake changes that help with velocity. I can only imagine it’s running super lean though. The full car delete (race only) on the lfx is netting 30 whp with no changes to the tune other than the warning lights turned off. The 3rd cat delete is worth all those muffler horses. They also see good mid range gains which is what I always want to see.ġ5 hp gain at 6000 rpm only sucks when you are always at 3k-5k which is kind of where our trucks sit when driving A little more fun. The camaro guys see some decent results which is odd. Guess I am looking for some of those old glory days with that old truck,

I had an '02 2500 Silverado Duramax that did not have a CAT meaders to an AeroTurbine muffler to the tailpipe and a K&N and when my buddy who had a similar year F250 borrowed my truck he was blown away by the power and it's ability to jump off the line. I do wish I could pull the CAT and start right from the headers. Shad76 Thanks for the info and the insight from your dad. My Dad is a mechanic with 40 years experience in GM vehicles and he firmly believes that anything you do to the intake and exhaust (after the CAT) only changes the sound, making people think their car/truck has gained more power. Instead of dropping $300 for a CAI, I would rather put that toward a Trifecta tune, where you could pick up more torque, horsepower and improved shift points. Sounds a little more aggressive, and my average fuel economy has been 18.9 mpg over the last year. Does it give the engine more power.? I really don’t think it’s noticeable. I’ve used them in all my vehicles and never had any trouble, they seem well made. I swapped the stock filter out with a K&N drop in replacement. It draws air from outside the engine bay so in essence it is a cold air intake. Jul 16, 2020The stock air intake is adequate and flows all the air you’ll need.
