New Roush install. Bucking/surging/hesitating. Logs attached

[kapiteinlangzaam]

Those are good numbers for a stock 727 setup. Your TQ numbers are really high though. You would normally expect around 550 at the tires with one of these setups.
Is the surging completely gone? If so, I might give my tuner one more shot at clearing that up and then switch if needed.
Also, does your car buck at all at slower speeds when it's cold?

The chart is in Nm. Equates to about 510ft lb at the wheel.

All surging/bucking/hesitating is gone. It drives super smooth. Every now and again the boost can be quite violent in 1st or 2nd (like too much all at once) but according to Lund that's an occasional characteristic of the Roush TVS blower. Happens seldom, so I'm fine with it.
