• Alternative Auto custom chip - to accommodate the increased boost, turn cooling fan on earlier and additional calibration enhancements
• Dyno time before and after all work has been performed to validate performance gains and fine tune custom chip

Total cost of this package fully installed with parts is $1395.00.

Even More Power
