    I ran one pull this morning, about .2 sec faster at 5.1 60-100 with the 2010 tables. Quick glance shows higher loads for me in the 270's. I agree with the initial roll in seeming weaker, less torque steer but hopefully I'll try it again tonight. 57* ambient and ~80% humidity when I left the house.

    MAF flow & freq looked close to the same on mine but I think I'm maxed out on the tiny turbo already at 33-34 lb/min.

    Maybe leave the 2008 tables in the mid rpm range and use the 2010's up top?

    Edit: N/M, Just looked and the low end changes are under 2k rpm, my pull started above 3500. Butt dyno's stink.

    We'll see what tonight brings.

    Two more pulls tonight with IAT2's around 90* and I'm 0.2 sec slower than base at 5.47 & 5.49 sec. If it made any difference here at all it seems a pinch slower in the heat of the day. May be flowing a pinch more but fuel trims went from dead on at WOT to +3 from 5k up with the 2010 tables.

    I'm going back to my stock cams once again.
