Feels lazy off the line… torque management?

I do plan on giving it a tune up (plugs, wires, fuel filter, etc…). I don’t know the maintenance history, but it has all the signs of being well maintained… I looked up the stock 5.3 torque curve and it seems to fit with what I’m feeling…

Definitely doesn’t feel like plugged cats, and it’s not stumbling or breaking up at all…

I’m leery of getting it tuned and killing the 4L60e, or the G80… I’d put my money in the trans and rear end first before adding more horses to the stable…

I always see it like this. My Tahoe currently has 330k miles. The dullness of the factory tune has allowed it to get this far. It’s never going to be a race car. But it will be reliable. Not something I would mess with.
