You have checked the hose from the intake to FPR, yes?

After that, I, personally, would do nothing (except stay out of boost) until I had a wideband. However, I do agree that you would have been knocking if you'd really been at 14 or 15 at WOT. In fact, if you had been that lean at WOT, you probably wouldn't have an engine any more.

 

Those words is exactly what he said. If my car was really doing 14 or 15 at wot my engine would be long gone. Yes I checked the hose and everything looks good. Its just really weird how the car got leaner and leaner at the dyno and he said he used 2 different sensors and still the same reading. The wideband would get installed sometime next week and I will try to do some logs, until them I have no evo

 

The fuel is overheating from continued recirculation on a dyno where the car is not moving. Also you're probably sucked out all the fuel from the half of the saddlebag fuel tank where the pickup is. Without g forces spilling the fuel from left to right and evening them out, this is what happens.

 

So I got my car back today after a few weeks. They finally got to install the wideband and they took it for a ride and did about 5 pulls on every gear and the A/Fs were perfect. First time I have a wideband so I wasn't to sure about what to expect so far I'm running :

Idle: 14.5-15.5 Car idles perfect and no bouncing RPMs
City driving: With partial throttle on normal driving like lets say 20% throttle Im running 14s.
WOT: As soon as boost starts during wot the A/Fs go down to 10.8-11.4ish

I just got the car back last night so I will be doing some logs very soon and post them up.
