I just went out and cleaned the MAF, checked all the vacum lines, checked the airfilter since it rained all day. The MAF might have had some dust but nothing major, all the lines were good and the air filter was dry. When I pulled the hard plastic line off the supercharger it had 2 drops of meth that came out, I have no idea but after checking everything it idles 14-15 on the a/f gauge then drops to about 12.7-13.0. I sent a PM to BYT a few days ago because the car is going through more meth just daily driving since the dyno day/tune adjustment but I haven't heard anything but that shouldn't affect it at idle so I have no idea.
I have the NGK plugs that come with the OTTP stage 2 kit, they have been in since the end of Feb. Gap is .032 or whatever it should be, I set it when I put them in.

Meth will not effect your WB O2 readings.
Have you tried forcing your car to run in open loop and seeing what the readings are? This will give you a good indication whether your O2 sensors are causing the issues or not. Do you have HP Tuners? Can you post a log?

Meth will affect the readings if the car is running rich, I know because the check valve was dirty again lastnight and I was idleing between 10 and 11.5 afr. Cleaned the crap out of it so the ball can seat closed and not im back to normal....

I guess I just haven't been injecting enough to make it affect the AFR readings. My apologies.
Yeah first off Meth will affect the readings of the wideband... Second off all , if you can't get ahold of nick for whatever reason. Get ahold of someone with hptuners and ill help you with your car.

I have tried to get ahold of nick a few times, by phone and PM's but there is no response. Part of the issue with my car is I keep getting little green crap in the check valve. I took the pump head off the meth pump and there was this **** inside of it. Im not sure what it is but I cleaned it all out so hopefully it will be good for a while. I like the extra power but I am tired of this **** clogging the check valve then it just sucks through the meth. I'll upload the pictures in a second so you can see. I know Chris (2010ss) has hp tuners and hes a local guy, he mentioned talking to you about getting a stock tune back on the car but i'm really not sure if I want to go back to stock just yet, still have to find a stock dp before I start anyway.

I bought the boost juice red/pink crap from summit racing. Looks like I will be going back to Devils Own meth, only reason I switched was so I could see how much is left in the tank a ittle easier. Any idea what causes this to happen?
