Hello, I have a 2008 C6 and just installed a Racetronix 525lph fuel pump module. These require you to either switch you oem fuel level sending unit over to the new module or you can reverse the values with tuning software.
So once was 3/4 full is now reading 1/4 full. Can anyone point me in the right direction on what needs changed in HP Tuners to correct this. Pump was already installed with this option in mind.
Thanks
