06 sc is going into limp mode, started after zzp stage 2 install.
3.0 pulley
60# injectors
stock box
stock exhaust
car jumped time and had lnf valves replace the stock lsj valves and the sc was salvaged from another ss to leave the hard to get pressed stock pulley on the original.
tb is fine tested it with key on engine off and it responds properly and there has been no cel other than a p0171 and p2229...12k miles on it since stage 2 still doing the limp. Very recently started loosing boost (11psi max on 3inch pulley) and throwing a p0103 cleaned maf/map sensor and replaced all vacuum lines leading into the bypass. Also as of today now throwing p2228 as well on the Baro sensor
any ideas on the limp mode or anyone have the same boost issue?
the car is averaging 35+mpg and drives fine other than limp and boost.
