Remove HPP3 Programming before KM install?
Just wondering if I should remove the HPP3 programming before I put in the new LT4 KM and then re-program. Or is it okay to leave the programming in and replace the KM?

You should be ok leaving it... one really has nothing to do with the other, and disconnecting power to PCM doesn't affect programming..

I installed a LT4 KM several months ago and didn't bother the HPP3 tuning before I did the switch and there were no problems. Like was said before, one has nothing to do w/ the other.
Thanks!
