This is intended for people with an HPTuners interface, it is intended for them to read their FSCM file and email it to us for modification. This will require using 1 HPTuners credit which can be found here.  This single credit is not included with the standard ZZP tune.

The modifications can include:

• Increasing desired (low side) fuel pump high load pressure
• Decreasing desired low load (low side) fuel pressure (to help big injector cars maintain a proper AFR at idle)
• Increasing fuel pump duty cycle (to help maintain full pressure at WOT)
  
• Remove active grill shutter codes

This is not a physical product, photo is for representation purposes only. This is an email HPTuners file update. Consult your ZZPerformance tuner if you have any questions regarding the process.
