yes, too lean. I would bring it back to your tunner. Sounds like something is wrong though.

How old is your O2 sensor? That is what happened to mine went it went bad. Fine when driving normally and eventually full lean when WOT.

Yeah either a bad sensor or something is off. Send a log to your tuner and get his impression on it. If he says your tune still looks good then I'd test that sensor. There is a video on how to test a sensor somewhere but basically you put some brake cleaner on a rag with the gauge running and then wrap the rag with the brake fluid around the sensor....Gauge so go from full lean to rich if it is working properly. If it doesn't then you have a bad sensor....you tube the test

good lookin out every one. i checked the o2 sensor cleaned it up a lil bit and did the test.

took a rag and put some gasoline on it and the gauge did go to 10 and went back down again. so i think its bad but i couple minutes to mess around. did about 3 wot runs 2nd and third was normal.. but im thinkin about ordering the sensor

thx for the help everyone

so i should run test again wit brak fluid...cause i did it wit pure gas on a rag and it went to 10 quick and then back.

I'm not sure what you are saying here? First of all, DO NOT use brake fluid. Use brake cleaner. When doing the test, did it go full lean after leaving it in the rag?? If yes, the sensor is bad. Get a new sensor and report back.

oops sorry i ment to write brake cleaner lol...yea ordering it now, will write back.

What you are describing is a faulty sensor. If your sensor was good, it would stay full rich as long as the rag had moist fuel/ brake/carb cleaner.
