Installed a Truck Norris cam kit,oil pump,timing set and a Trailblazer i6 converter in my 06 Crew cab. Love the cam and the converter was exactly the perfect choice to give it a little more stall and not be too loose!

I had it tuned by my installer. He has an HP tuners account. Mileage doesn’t vary from stock. The mild converter does the truck justice!Couple of questions:
1- How did you tune it to run well with the TN cam?
2- Did you notice a significant change in MPG?
I'm thinking of installing the TN cam in my 2005 Yukon 4x4. Planning to keep the stock converter, upgrade exhaust, get a Airaid intake tube, and use an HP Tuner to tune it.
I've already opened up the stock airbox for freer breathing and I plan to keep it. I cut a bunch of holes in the bottom of the airbox and the tray, connecting it to the fender, and sealed from the engine compartment with foam. Since this is my daily driver, and I plan on taking it on trips, including out West, I want the flexibility of being able to find a clean air filter anywhere in the country. From what I've read, with the mods I did to the airbox & tray, there would me minimal, or no, improvement with an aftermarket "cold air intake" system.

What kind of engine are you running you’re out flowing the stock box and larger filter bCouple of questions:

Make sure the liner stays in place. My wheel well extensions for the hd chassis tire stick out are tied into the same spots as the clips for the wheel well insert. My fender is rusted badly in these spots. The clips that holds to the tray below the air box is doing a lot of heavy liftingRunning the stock 5.3, no mods (yet). You're probably right that the increase air-box capacity won't make a measurable difference; it reduces restrictions, but not enough to make a noticeable difference. I'm getting everything I can for free (except for my time)!
You make a good point about water; thanks.
The holes open up forward of the inner fender, so water from the tire should not be able to get in there.
