BlackBear Tune 2015 Denali XL

[JennaBear]

Autocal or inperson are your options, due to the computers used in your vehicle.

Same above options for your vehicle.

Typical gains are 10-15HP, but biggest things are much improved throttle response and better shift patterns.

That's interesting, as every Tahoe I test drove was a little "slow" to respond to the throttle. Mine is no different. So...the result will be a more responsive throttle, but not so fast that we will be eating too much fuel?

MPGs should increase, provided you are easy with the right foot.

Depends where you driving, if every day you seat in traffic hours,forget about that. Mpg is going down.
