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 pressure at high load.
-
Decreasing desired (low side) fuel pressure at low load. (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 (P059E)
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.
