Idle drop after rev up negitive timing for a few then back to normal.

tune your maf and vve to exactly 0% (even if your tune is set to maf only)

MY stft are + or - 2% now and it still has the big timing dip so if I get them to 0% the timing dip will correct it self?

maf only AND VVE only? you tuned your VVE at 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900 RPMs from .4 to 1.0+ PR?
