Warning:
The Phearable.net Ktuner Stage 2.5 Tune WITH GOD MODE should only be used with a RACE downpipe.
A crackle type tune requires extra fuel and negative ignition timing to create a crackle effect during deceleration which can cause damage to engine components after prolonged use. We are not responsible for any damages to you or your vehicle.
GOD mode calibrations are prone to use more fuel then non-god mode calibrations due to the nature of what needs to occur for god mode to work. The factory L15 headstuds and rods are known to be weak therefor headgasket and rod failure is a risk when pushing the engine hard.

Note: All sales are final. If you order the tune for a vehicle other than a compatible vehicle you cannot be refunded.
Tune files are not transferable. Support is provided to the original purchaser only. Tune files are locked from editing a majority of parameters. Tune files do not include any tune revisions or remote tuning.

*PLEASE NOTE: For Off-Road Race Use At Sanctioned Events Only.
