Planning ahead, couple of questions Getting ready to help a friend do some work on his 2002 Z28, which we have already tuned using HP Tuners. The car runs good now, but we are looking to do heads and cam in a couple of weeks in this car.
My question is, I know I will need to go through the tune process all over again, but is there something I should be prepared to do ahead of time to get the car running well enough to be able to tune it completely? Or Should it run well enough after the swap to be able to do this?

Really the cam is the question, how bad does it whack
the low end. Post-install mine needed a lot of pedal to
catch and fire up initially, it couldn't do it with the VE
tables as-was with throttle closed.
I would look through the repository for something close
in hardware details, and at least have the files handy
on the laptop if not a best-guess tune already pushed
into the PCM. Idle and low-end airflow settings are the
biggest deal, the rest will probably not be too messed
up.
