Swapping intake manifold & throttle body on a 5.3

[JJKNIGHT]

Well my new girl, DYNO'd 305/345 at the wheel. Been averaging BEST of 26.5 on the highway. 19 around the house on 93 SU2000.
Stainless Works Headers and xpipe duals installed couple of weeks ago.
Having some sensor issues but I'm working thru it.
She really sounds great though.

My Local guys at SMART CHEVY of WHITE HALL, AR ordered and worked me in to the shop and got both upstream O2 sensors swapped with OEM AC Delco and she's purring like a kitty.
Thanks to Chris and Monnie in the Service Team.

Wait, what year is your truck?

Do the engine mods you installed translate to 2009-2014 engines?

@Charlie207 I love the signature about the broken door pull. I didn't realize that was a customization feature-always considered it a GM standard option on the Tahoe....eh, learn something every day....Guess mine is "custom" then!! Lucky me!!!!!

I bought some Ready Rod and silicone caulking when I first bought the truck (came that way) in an attempt to fix the door-pull issue. I've been too lazy to implement the fix.
