Mid to high 200's without the intercooler/pulley drop.
Another drop with the aid of the intercooler and you'll be high 200's to low 300's.
Biggest issues around this power level seem to be the 1-2 shift, downshifts/skip shifts and hooking.
1-2 shift for me got very sloppy around mid 200's at the wheels.
Downshifts are very hard on the entire system. So either play with the tune to have it downshift sooner or manually move the shifter into the gear of choice then push it back into drive once your foot is to the floor.
And hooking is just downright mean to the input shaft and chain set. Spinning is better for those components, but any one wheel peel is hell for the differential.
