'03 Civic Hybrid

Anybody done the recent recall to 'correct' the lean mixture that could affect catalytic converter? Mileage and performance has gone down the toilet. Dealer checked with their tech-line and supposedly they are getting a lot of complaints.

I had mine done last month, along with my 40K maintenance.
MPG dropped by about 5-7.

Then I realized that I forgot to suggest the higher tire pressure and sure enough the rascals dropped them way down to 32.

I pumped them back up again and my last tank was a record-
941 miles and 69.2MPG over the single tank.

You might want to check that.
