Already tuned with IE but hungry for more power? Adding hardware and upgrading the required stage is easy with your IE POWERlink Flash Cable. You only pay the difference in tune cost when upgrading stages with no extra fees. All you need is your POWERlink serial number (found on the back) to add upgrade credits to your cable.

Both the ECU and TCU tunes are absolutely worth it in my opinion. Turns it into a different car.
