So I've had my supercharger installed for about a month now. And a couple days ago, I get a CEL in my dash, my SCT says the codes are P0171 and P0174, says too lean. I did some research and this is what I got:

Possible Causes:

• The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
• There could be a vacuum leak downstream of the MAF sensor.

Possible solutions include:

• In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
• Inspect all vacuum and PCV hoses, replace if necessary
• Check for a dirty fuel filter and proper fuel pressure.

So I'm going to try that but is it ok to drive with this? I had the system tuned at Excessive Motorsports in VA, and I'm in NY right now. Should I go back to them or should I find somewhere here in NY to retune? Would a dealership be able to check/ help me out? For now I'm staying out of the boost area and driving nice and easy, but is even that going to hurt me?

Thanks.

clean the maf and clear the code and see if it comes back. i get the same 171 code on my 07 f150. changing the fuel filter helped, the code came back less often. i finally ran a a bottle of fuel injector cleaner through and that fixed it. now i just run a bottle through every 6 months and no cel.

also its safe to drive that way. the computer has a set afr it tries to run the motor at. it also has a certain percent of fuel the computer can add before it thinks there is a problem. when it goes beyond that percent the computer assumes something is wrong and sets off the cel. afr is still good but the computer is telling its adding more fuel then it thinks it should have to and thats why you have a cel
