What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Mickey_7106]

Found this on Corvette forum

LS2 and 2008 LS3 are the same throttle body. 2009+LS3 and LS7 are the same I believe.

LS2 and 2008 LS3 have a silver throttle blade
2009+LS3 and LS7 have gold throttle blade.

They are not interchangeable

Bolt pattern is the same for LS2/LS3/LS7--I'm not sure about the LS9

I believe the measurement is taken at the opening shown here. (this is my throttle body on my 2008 LS3)

Was it pnp or did you have to modify to fit?

it's plug-n-play

***if you have the factory intake and change just the tb you might have to trim the plastic a little depending on your engine

The throttle body doesn't void the warranty?

no neither did the cai, when the dealer installed the motor they put both back on it and didn't say a word, I haven't had to have any warranty work done but it's been to the dealer since then for misc stuff and they never said anything then either.

Late to the party, but I wonder what Wes, took out the cat? Sticky fuel injector? You can turn them on and off and check your fuel pump trims too. Your LTFTs @ 7, if they stay there for a long time are off. What's your alcohol content? If that number is off, you can reset the Fuel Trims and Fuel Composition and start her over again.

and the alcohol content is 2% currently, mpg bumped up to 9.8 today, historically it's been 10/10.2 ever since I have had it even with the old motor

Well, it's nearing time to purchase my shorty headers. I'm down to the following choices, and would like any opinions you guys have. I know @kbuskill has the JBAs, but they're the costliest of the bunch. Gibsons are on sale, and that's where I'm leaning right now. Any input would be great.

I went through the same process... I went with JBA because I found a guy with a brand new set that had sold the truck he was going to put them on so I got a great deal.

I don't really think there is any real difference between the Gibsons and the JBAs... they look identical.

I would definitely stay with the 1 5/8" primary tubes though... you don't need anything bigger for a NA 5.3l.

Other than making the engine bay look pretty and noisier, those shorties won't do anything for you..

Have you tried them or are you just regurgitating the same internet wives tales that you hear all the time?

Should be covered under the Magnuson-Moss act unless dealer can prove said parts are the culprit for said issue

[Mickey_7106]

No i have not and im sorry that some one convinced you otherwise.

Too funny... also not worth arguing over... besides, everyone knows that it's long tubes or nothing right???... it has to be true because it's on the internet... lol

 

[Mickey_7106]

Funny, you bought your shorties based on promosing numbers from the webz...

it has to be true because it's on the internet... lol

But anyways, i guess it all comes down to what you want to accomplished. I for one am always on the highway. I rather have power up top than dow low. Theres plenty of power to get this tank moving from a stop
