CUSTOM tunes can only be performed in person or with equipment rental. Please be sure that you are local or are planning to travel to the Farmington, MO area before placing your order if requesting a tune in person. If you're planning to be tuned in person, this page is meant for representation purposes only, as payment will be accepted during the tuning process. If you plan to rent equipment to be tuned remotely, you are required to send a message from the Contact page beforehand, and you must recieve a response to be added to the schedule. Do not purchase equipment rental before receiving a response. Failure to follow these guidelines will result in a delayed communication response, delayed order processing, and a non-refundable fee (see details in Shipping/Returns/Refunds section) is assessed.

2.0 cars typically see gains of 50+whp* and 65+wtq* for stock turbo and well beyond that for upgraded turbo depending on fuel type and aspiration. 3.8 cars typically see gains of 35+whp* and 25+wtq* depending on fuel type and aspiration. Don't be fooled by other tuners and their inflated numbers just to be disappointed when you hit a dyno or race your friends.
