Chevy Tahoe Mods

[Zygocrybiate]

Im seriously considering putting on a new intake manifold and a hot cam in my 5.3 tahoe, im just wondering what the benefits and downsides of modifications like these would be. Im hoping to increase the power without impacting the mileage to bad, one or 2 mpg isnt a big deal. From what i can gather, the manifold will increase power and mpg, from the better air flow, and the cam will increase power as well. But how does it impact the mileage?

Just get a black bear tune and save the time and effort. They are vendors here check them out.

What will that give me for performance and mileage?

I wouldn't do that in a big truck like your Tahoe. You'll be throwing away 50-75 ft pounds of torque down low and almost all the power you gain is at 6000+ rpm.

Just do the swiss cheese mod on your stock airbox. Nearly the same airflow increase there as a $250 system and its free...

I put a glasspack on my yukon and have noticed that it breathes better now, and has a little more power. After a BB tune, possibly an aggressive one, you will be set to go.

Wow, has anyone ever properly modded your vehicle before?

Are we really giving out advice like "just chop up your air box, it's the same as an intake kit."

And "don't install an intake and cam, you will loose torque, and all your gains will be over 6000 rpm?"

Damn, I might have to second guess coming back on this forum...

First of all, before you mod, you need to decide what you want to get out of the changes.

A quality cold air intake, properly planned cam, and the right intake can make the right power you are looking for.

I suggest find a local shop that has a good reputation and discuss cams with them.

Don't cheap out on an intake, get a KN or GM performance. Nothing with a metal tube.

And get a second opinion.

Wow guys, you should be ashamed.

Intake, Exhaust, If you have a clutch fan swap it out for electric fans, Corvette servo, Blackbear Tune and you will be happy.

If you want more after that:

Long tubes, cam, hardend pushrods, possibly valve springs, lifters, stall and you will be really happy.

I have pretty much everything done that I mentioned and I gained about 100whp over stock.
