The internal setting is accessed by removing two screws and the cover on the back of the unit. The setting adjusts the additional boost over stock. With a setting of 100 the unit will request an increase of 4 psi over stock. The actual boost will depend on several factors including the octane of the fuel. On the later model years a 2D25 manipulation prevention code can be set if the setting is too high. It is a good idea to check with a scan tool to
make sure that code is not being stored. Turn down the setting if necessary. |

It also features a 36” wire harness so the unit can be conveniently located in a place where it is easy to access for adjustment.

When set to its maximum boost setting of 100, the Turbo Tuner 2 will generate 4 psi of boost. With high-octane premium fuel it is capable of increasing horsepower by 55 hp and torque by 60 ft-lbs. |
