If it is an exhaust leak? Is there anything I can do besides replacing the up-pipes? Those puppies are expensive.

Actually, the Ford replacements will run you about $100 in parts. The labor is pretty intense (turbo r&r at 1.8 hours plus the time to do the pipes).

Cody, I was able to get what I thought was turbo surge around 25psi just playing around in the perf tune, but it was more of a *chirp chirp* sound. The sound I was getting at 15psi was more like the sound you would hear if you blew into a table fan. Why would the turbo surge at 15psi? Isn't that really low psi for it to do that?

YouTube - 7.3 powerstroke turbo surge, turbo stall, compressor surge, or normal wastegate blowoff???
This is the closest sound I could find to what I was hearing at 15psi. Go to the 1:00 mark like he says in his description.

Wow, now I'm worried! If in fact, that was turbo surge, and I drove the heck out of it not really thinking it was surge, what kind of damage might I have done? How would I check for damage?
