don't waste your money. all thosr thongs do is send a false afr reading and can cause engine damage.

Nothing you can do unless you start ripping the engine apart, all that CAI, tuner etc etc wont do you any good, Im in the same boat as you with my 08.

Do yourselves a favor next time and don't get the 4.8L slug engine in a truck.

I bought a hypertech programmer on autoanything for $254 after their event code EVENTS15 and Hypertech's $100 sale. I couldn't pass up that deal, maybe I'll notice a difference. At this point my 2010 silverado crew only has an airaid smooth intake tube attached to the stock air box with a K&N stock size filter. After this tuner, I'm looking to get either true duals instaled with an X-pipe or just a single in / dual out; I'm not sure how much better the true duals (or worse) it should be over a single muffler.
Also, on this thread you guys mentioned a cam upgrade. How intense of a job is that?

Supercharger...big initial cost but with a healthy engine and a lower boost setting the reading that I've done points to a safe 90-110 hp gain

So after driving around for a week and changing the tune program three times, the hypertech programmer was the most noticeable difference for my money. I kept the rev limiter at 5000, but increased the shift firmness to 75%, and shift points to -400, -300, -300.
