Tuned: 2ng gear leaner than 3rd and so on?
What could cause my 2nd gear to be leaner than my 3rd and 4th gears. With little difference 3rd and 4th are pretty much the same. 2nd gear however is about 11.8, and 3rd is 10.5-ish at WOT. My tuner said he had no idea why it was doing that. Is it his tune or something else. Please chime in, as this is getting costly.

From the dead. I have figured it out. I paid the tuner to do my injectors because it was a two hour drive. It looks like he didn't Vaseline the O-Rings on the injectors/insulators. I noticed a hiss last night when I pulled over and popped the hood with the car running.
It would appear that because it's been warm that every time I have been out of my car with it running either the ac fan or the radiator fan has been on blending in that sound. One of the insulator O-Rings was torn and viola, vacuum leak. So now it's waaaay rich, but it's obvious by the change in the tune now that the leak is why the afr was wrecked.
