We are only offering our full Performance tunes at this time.
Our tunes are our full performance packages for most naturally aspirated cars: whether completely stock, or with catless exhaust, long tube headers, m60 manifold swap, E85 fuel, etc. Simply mention your mods, and we tune accordingly.

Being unique is important, so we are also offering some experimental features, like pops and bangs, etc.

-What's the process?-
You are purchasing our remote tuning service. After purchasing your tune, you will receive an email with our software download and instructions to begin the tuning process. It is a very straight forward process.
You'll essentially check for any codes the car may have and save them. Then pull a backup of the ECU as it currently sits and send it in to us. We'll then build your tune, and send it over to you for uploading. It's easy as that!
