same as with any car with cams

expect (with say the 264 deg sticks, both intake and exhaust):
loss in low rpm performance, under say 1800 rpm **** all pull, quite rough. under 2300 not too bad
around 4000 expect a big jump in performance, anyone been in a 2zz-ge equipped car when they come onto lift, its like that.
maybe a tiny ammount of gain in spool.
expext your exhaust note to be louder.
rough (read much tougher) idle, a bit lumpy.
you can run these cams on stock ecu (i ran my car in on stock ecu with these cams)
how much change also depends on your cam gear settings(if you have adjustable cam gears), I also have adjustable cam gears and have 2 deg advance on the intake and 4 deg retard on the exhaust, ill be playing with these settings more to get the optimum settings, the more you adjust the cam timing the rougher you get down low and the lumpier the idle, no big dramas though, if your car is your daily you could live with it so dont stress. 264 are generally regarded as the biggest cams you should have in a car regulary street driven.
