Pulsar tuner

[muskratnarf]

I just purchased a pulsar tuner for my truck and am about to install it, and am wondering if I need to remove my speedometer calibration that I did with the hypertech calibrator, is that considered stacking tuners? I know I can calibrate tire size with the pulsar, but is it necessary? Any help would greatly be appreciated

You shouldn't need to remove it.

No need to

I would personally remove the Hypertech and use the Pulsar. I'm not sure if there would be any issues if left alone.

The hypertech just plugs into OBD2 port, you make the changes, then unplug it. It's not always installed. It would be no different than having the dealer change the tire size, or using the TazerDT or even Pulsar to change the tire size.
