Keep in mind the tail pipe sniffer is 0.5 leaner at IPS (proven with ecu hooked up to lap top showing widebands) then the OEM front wide bands where the car was tuned off of. The tuners dyno is 12.5ish with his tailpipe sniffer. IPS just must be old. It's not like the car went back to stock (I've heard it happen to some other 13 on here and the before was rich, not lean).
