The stock tune is really lean at tip in (.95 tip in to .86 up top), but it's definitely not .98-.99 lambda.

I'm .92-.88 on e47

^^ first off, we're talking at wot that being too lean. At idle that's obviously where you should be. If you're seeing 14.7 at wot then you've got other issues brotha. Second, your uego clearly disagrees with your interceptor.. lol

My AEM gauge doesn't work. Actually it never worked since I bought the car last Monday. When I start the car it does an initialization but after that it just shuts off and display nothing.
I am thinking it just isn't connected correctly. I didn't know the previous owner and I've never modded cars before, so I when I get some time on Saturday I will investigate the sensor.
