Well, I found after swapping out sensors. My problem is not in my tune, good thing I did not make any radical changes. The AEM wideband O2 sensor is bad after only about 10 runs. Called AEM and they say high EGT's. I use an aircraft EGT set up with 6 individual sensors, I do not have high EGT's. Then they say the sensor needs to be 36" from the exhaust port. Not possible, have they ever seen 935 headers and twin turbo set up. So basicly the sensors will not survive under high boost runs, so I need to find a source where I can buy them at a descent price as it looks like I will be replacing them often or turning off the computers ability to make changes based on the wideband readings. Have seen somewhere a spacer which is suppose to reduce some of the heat to the sensor but can not recall who makes it.
