TPS is steady now. Looks like you found your problem with the flaky voltage.

If I followed this correctly- you might want to now log the TPS 5v for a run. You changed the 5v source but what was going on with the old 5V source?

which is the terminal on the analog block that Bob does not like to use?  Ground or 5v?

A lot of broken parts does not make you a racer; it makes you a slow learner.

Original problem was that the boost signal was jumping all around from 20 psi to 10 on the log that was in the first post. I thought that I may have a waste gate actuator that wasn't holding the boost.  Earl asked if I had the MAP sensor power source spliced into the TPS, which I did.  TPS is now back to its original configuration with no Y harness installed. MAP sensor now has a new source for power

I hope someone else knows because I'm using both.  I hope it's the ground...

I believe Bob does not suggest using the PL grd for anything other than very low current devices
