you should be more worried about running lean, not ritch. Ritch will make your motor run poorly but it is not certain death. Running lean is certain death.

Also, the O2 reading on the timer is completly inaccurate. You need a wideband o2 sensor and gauge for a correct reading.

The old rule of thumb in the days of the PFS purple ecu according to most on the old big list was .88 under boost. if it's lower than .88, then you need to fasten it up until you can get it tuned proplerly.
