The Sniper uses the newer 4.9 sensor whereas the HP, Dominator, Terminator use the older 4.2 sensor - maybe the newer sensor simply does not need a Holley calibration to work as expected? I assume the Terminator X would use the same sensor as the Sniper since it also uses the 4.9 sensor.


The 1st sniper used the 4.2, I guess they updated, the HP does not use a 4.2, it is a Holley specific plug & calibrated, I use the Holley NTK sensor on my HP efi
