Have an update on this old thread. I purchased this module and it is awesome. It’s almost like it woke up the tractor. install was 10 minutes as it is just plug And play. It attaches to the plug on the fuel rail then that plug attaches to the unit. option at +15% +20% + 25% +30% +35%. the default is 20 bringing a 5460 to around 64.8hp.
