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

Man that would be cool. I'd love to slap one on my 07 but $1,000 is a lot of monies. I wonder how big of a pain it would be to tune for the bigger throttle body as well.

go with EFI Live from Blackbear and new tunes are free for as long as you own the vehicle... no they’re not paying me to say this. Anytime I add anything new... just datalog and send in the file

I was pointing out the price. Anywhere I've looked it's going for over $999

Too good to be true? You’ll need their 102 mm TB to go with it to gain 25 HP, so about $1000 give or take.


”Designed specifically for GM 4.8/5.3/6.0L cathedral port truck engines and cathedral port LS1, -2, -6 race applications where hood clearance is not a concern, the FAST™ LSXRT™102mm Intake Manifold follows the path chartered by the original FAST™ LSX™ Gen III Intake by featuring a modular design that allows for easy porting and disassembly and a runner design that yields an incredible 25 peak horsepower gain over the stock intake, on a stock 6.0L engine with a Big Mouth 102mm Throttle Body™. And similar to the LSXR™ 102mm Intake Manifold for cars, the LSXRT™ features the ability to remove individual runners for modification.

The LSXRT™ is constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While it features a 102mm air inlet that was designed for the FAST™ Big Mouth 102mm Throttle Body™, it can also be used with stock 90mm or aftermarket 92mm throttle bodies (78mm three-bolt throttle bodies require an adapter). Other features include integrated nitrous bungs and precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues. Some GM truck models may require the FAST™ 92mm or 102mm throttle body.”

I may just have to. I bought HPTuners so I really don't want to but I may just do it. I bet the intake mani and big TB would mesh well with the cam! I wonder if you can run the stock airbox with the bigger throttle body?

It doesn't say anything about how much torque this would increase but I wonder... since this in effect lengthens the intake runners if it would increase torque.

I base this off of my knowledge of the old tuned port injection engines. The long intake runners created alot of torque.

I have often thought that it would be cool to have a long runner intake for the Burb as I don't really care about WOT HP but I do love torque to get the big girl moving.

This is a very interesting thought. I wonder how that plays into the manifold geometry. Kinda like how header primary length effects power bands.

Very interesting indeed.

In all honesty though... I always thought the TPI intake looked cool as can be... kinda like headers for your intake... lol

Have you seen the Edelbrock Cross Ram for the LS3 (or I'd hazard a guess any other LS that has the same ports)

Yep, some of the best looking engines ever! And the old LC2 as well!

That looks awesome, classic look too!

I thought I only needed the hybrid tailgate if I wanted to run the hybrid spoiler.
I would love to do that as well. So so so much.

you do want to get rid of the security hole?


anyone can go inside anytime they want and take your stuff..
