As many people have probably learned, the 6. 7L has a different rail pressure sensor than the 5. 9L used. ISSPRO's Performax & EV² Rail Pressure gauge harnesses are "universal", allowing them to plug into either sensor. We now make the rail pressure gauges with the software for the 6. 7L curve. The part number is the same as the old rail pressure gauges (in the various styles) but replacing "288" with "289". In other words, the EV² 6. 7L Rail Pressure gauge in the white face/red pointer (factory match for 3rd gen Dodge) is R14289.
If you purchased a rail pressure gauge previously for your 6. 7L, drop me an email and we can arrange for you to send it back to be reprogrammed.
