    You are commanding 12.7 AFR with 17psi boosted car wich is very dangerous (should be around 11.4 )
    start with B3618 set it to 11.4
    I've already made VE adjustments to get the AFR to 11.3. I am in the process of tuning WOT so any suggestion are welcome. The Main VE is also a work in progress. What else should be done to the PE tables?

    I agree with Wesam, I just nowgot home and looked at your tune file and I was a little shocked, PE is set to EQR 1.00 and OLFA is set to EQR 1.13 (AFR 12.95)...

    for boost you want fueling (PE and OLFA) to be as rich as EQR 1.28 (AFR 11.4) as Wesam said.

    Some of us do this: we use OLFA for un-boosted EQR (ramp up to EQR 1.18 in upper columns), and use PE for boost (EQR 1.28) by setting B3613 to 105 kPa.


    As Wesam said, VE needs alot of work (it currently specifies less air than stock!!), you should start with stock and add 20% maybe more; and edit the Boost VE table to continue upward.

    When I had problems with the wires burning with my headers I used a role of 1" header insulation and wrapped them several layers and then put the socks over them. I had 3 cylinders (3,5,7) that would fry the wires. 60,000 miles later and now problems. I also keep 2 additional wrapped and socked plug wires in my glove box but have not had to use them.
