I picked up a car with neptune. It is the older non rpt. I will be boosting it soon and would like to know what kind of boost control it can support. can it support a boost "switch" or even boost by gear?

 

Both. Go visit the forum or download the RTP software to see the full extent of the features.

 

Your neptune tuner will have to tune the vehicle for you using the pwm boost control features of neptune.

You will have to have PWM EGR components installed into your ecu. You will also have to purchase the proper boost solenoid etc.

Contact your local neptune dealer for more information
