2017 Tahoe hauls ass.....

[TahoeFL2017]

I rarely put my foot really into it, but still am pleasantly surprised how quick the 5.3L motor gets my Tahoe moving.

Sweet spot seems to be from 25 mph to 75mph, coming out of a Charger RT Hemi, its not the same,(Charger would break the rear tires loose on a 30mph roll) but still am impressed.

6.2l I know is faster, but I did not want to be stuck with 93 octane, or Denali options that I don't need.

Awesome, I totally agree that the 5.3 gets moving. Glad you're enjoying it.

I too am pleasantly surprised. Let’s be honest, nothing about Tahoe screams speed, but she goes well. Now, to get rid of the 111mph limiter to stop going limp would make it even better

355 Horses and if you add the sensor and related hardware for Ethanol, she'll make 380 horses on E85. Computer tables and wiring and plugs are already there.

As long as the road is smooth and straight.....

I concur. Haven't even added headers and exhaust yet. A simple AFM Cold air intake and the BB Tune and I can get her to squeak off the line when i mash the pedal. Firm shifts at 6k RPM too.

My 18 Tahoe has a lot more power than my former 02 Tahoe and my current 08 Silverado. All with the 5.3.

My 2018 Tahoe is actually kind of a dog. I’ve been wondering if any of the tunes do any good or not. I had a Predator Tune on an older Silverado, but, was disappointed by its performance, surprisingly, because I had great luck with a Predator Tune with a Challenger I had previous to that. Now I’m afraid to try a Predator Tune again for the same size motor I was disappointed with previously. Never using Blackbeard, I’m also afraid to try them.
