Dyno Services & Tuning
Our in-house Dynojet 248 chassis dynamometer is capable of measuring up to 2000 HP and 200 MPH. We utilize the most up to date WinPEP Dynojet software calibrated for our specific dyno. All dyno electronics are current and serviced. Safety straps are always pre-inspected before runs. Vehicles go through a mandatory preliminary safety inspection performed before any session. A safe viewing area is available above the dyno platform for video and pictures.
All of our tunes are designed to not only make great power, but to deliver unsurpassed drivability. Whether you are looking to make the most power, increase fuel economy, or just improve the way your transmission shifts, we can help. From completely stock vehicles to highly modified street and race cars we have you covered.
All Underground Performance custom tunes come with post dyno support for any changes or customer requests at no additional charge. As long as additional mods have not been performed.
Vehicles with aftermarket cams, heads, forced induction (non stock) or required MAF or other sensor scaling etc will/may incur additional charges.
Dyno tuning sessions for heavily modified vehicles will be priced on a per vehicle basis.
Discounts available for other shops that may wish to use our facility for R&D, to tune or set-up their customer vehicles, etc.
