Power Adder Type *

Please choose the type of power adder that has been installed on the vehicle.

Add Nitrous Tuning *

Nitrous tuning is unique as we are required to service the consumables of the vehicle (fill the bottles, change plugs, stand-alone fuel and fuel pressure adjustments, jetting changes, etc.)

* Nitrous tunes average 2 hours, but sometimes take longer due to the complexity of the system and build. This service includes the first 2 hours, but additional time may be needed and would be billed separately.

Add Flex Fuel Tune (E85) *

This includes tuning for pump gas, and then tuning E85 on vehicles with flex sensor installed.

Is your GM Vehicle 2017 or newer? *

There were changes introduced by GM for 2017 and newer vehicles which makes the licensing and tuning process more expensive and more difficult than previous years.

2020+ vehicles with the T93 Transmission Control Module are not eligible for trans tuning. Hoston House of Power offers the T93 to T87A swap for customers looking to enable trans tuning.
