Just got my ECU back from Weller Racing - they reflashed with Stage 1 - I reinstalled it this last Saturday and What a Difference! Should have done this a long time ago. I'm not sure how shipping would work but It may be worth it to get a 2nd ECU for your SS YXZ and ship it to get flashed by Weller. That way you won't be down in the meantime
