80 psi.... crap that's bad. Pistons should be within 5% of each other in a healthy engine. Could be many things... burnt or damaged valve, bad score on the piston wall, broken piston ring... none of them good.
Does sound like too lean, or the tune was written properly for the weather as it cools off (depends on where you live, its not cold here in Georgia yet) and it's adding way too much timing (Roush was/is doing this with some of their 2004+ F150 tunes).
