On supply of details of your car, we create a Custom Tune to your specifications, and load it onto a chip ready to for you to plug in within 2 business days – no long delays. Installation is simple, and takes less than 15 minutes – see Installing a J3 Chip for instructions.
Use the Order Notes field in the Checkout to supply us with the details of what you need in the tune. In your note, please include make, model, engine and transmission type, any engine or fuel system modifications, the fuel type and optionally a dyno sheet(s) showing AFR & RPM.
If your car is highly modified you should understand this is a base tune done to your specifications. It is not a substitute for tuning based on data logs, and may not run perfectly without some tweaks.
