I got my Precision turbo installed today.

I also installed a replacement exhaust pipe (original had a cracked weld). I had a hell of a time getting that new pipe tightened up against the engine head without leaking. First time I started the engine, there was a loud/obvious exhaust leak. Spent a lot of time re-tightening the bolts, tightening each one a bit at a time to try to evenly tighten the whole mounting flange. The obvious exhaust leak sound is gone, but I'm still paranoid of having an exhaust leak. Data logging didn't help my paranoia either, because its showing that I only hitting about 7.5 psi boost now (was hitting 8.2-8.4 psi with the Garrett).

So I've driven a bit with the Precision, but I'm going to withhold sharing any thoughts about it until I figure out if I still have an exhaust leak somewhere.

That number doesn't make any sense. Did you type it correctly? I just looked at a data log (old log, from when I had the Garrett installed), and I see values as low as about 10.27 at full throttle, high rpms.
