wait until you add a supercharger/catback/tune.


then its really fun
but then you will want/need even more power

I have a 2017 Tahoe and I need more acceleration what can I do?

all depends on your budget & speed/power needs


as stated previous post,

add the sensor and related hardware for Ethanol

(e85)
*but know although the fuel is cheaper, it takes more to go same distance as reg. fuel (i've read 40%)


CAI, catback & tune (BBP or HP tuners[ both seem to be more popular than other options])
LT headers
go inside motor & massage it
boost it (supercharger or turbocharger)

the sky & your wallet are the limits LOL

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.

Blackbear is great. You can get retuned for life. Also after tuning if things seem off or not right they will answer your concerns and modify your tune to get it spot on. They use data logs you provide to customize the tune to your specific vehicle and how its running. Its a simple process and really wakes these vehicles up and also gets them shifting so much 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.

What all besides the sensor is needed on these newer tahoes? Pump and injectors?

Can't say specifically but this is where I learned about it. There was another thread that had the SUV specific parts or you can ask Rene.
