Hondata

Ok so I have the car tuned accordingly and the car was running strong. Air fuel ratios were where they needed to be.The next day I start the car she was running lean at both full throttle and part throttle. Any suggestions on what would have caused this? Thanks for your input in advance.

Specs are....

B16A2

Wiseco 11:1 Pistons
Eagle Rods
Skunk2 Stage 2 Cams
BuddyClub Valve Springs
Toda Retainers
Blox Intake Manifold
68MM Throttle Body
Intake
4-1 Header
2.5 Magnaflow Cat
Catback Exhaust

Any help or input is greatly appreciated.
Thanks.
