CEL - System too lean (Bank 1) and MAF sensor

[47_MasoN_47]

Little bit of information to start

2009 Yaris Sedan
Blitz supercharger (installed for 3200 miles)
53000 miles total
AFe Short Ram intake

I just went on a 350 mile trip for work and about a mile from my house I was trying to beat some traffic so I got on the throttle a bit too hard and the car was pinging the rev limiter briefly (maybe for 1.5-2 seconds) while in a 2-wheel spin. Shortly after this I noticed a CEL. I was less than a mile from home so I went ahead and drove it the rest of the way. I connected my ODB dongle at home and it had:

1 current fault - System too lean (bank 1)
1 pending fault - MAF sensor

I cleared the codes and they didn't come back immediately. I went ahead and turned the car off because I wanted to come eat dinner and whatnot. Do you guys think it's safe to continue driving and just wait to see if the codes show back up or is there some preventative maintenance I need to do? My filter on the AFe is pretty dirty.

If you are running the Blitz fuel controller, as opposed to a F/IC, etc. then your issue is likely the intake. If you look at ltnoogie's old thread about his Blitz install, he had issues with running lean when using an aftermarket intake. The Blitz fuel controller is only designed to work with the restricted flow of the OEM intake.

How much power did the supercharger give you?
