Okay, updates... Wideband is for sure cooked/fouled. I have a new one on order.
Changed a couple things in the tune today and problem is definitely getting better but still there. Checked voltage today and it is 13.9 volts so I dont know!!! Anyway, It is for sure tune related. I will post tune in a bit and maybe figure this out.

Delta- I used 1ga cable for power and grounds.

 

any updates, i have similar problem

 

Problem resolved and was attributed to my maf sensor. Maybe the final increase in boost from spinning the blower to max rpm was just too much??? Anyway removed maf and went SD and the damn thing runs better than it ever has before!!! I really am impressed with speed density tuning!! Car feels so much crisper everywhere...

 

Awesome, I'll be interested to see what it does at the track now. Bob
