Would too small of a turbine wheel cause power to drop off substantially or simply flatten out? I have a t3/t4 already in place and I'm using a t4 cojmpressor with a .60 a/r and a t3 turbine with a .63 housing except the wheel is the same as the one from a .48 housing. I switchedc cuz I noticed that my power was really dropping off with the .48 housing (and stage 3 wheel) so I got a .63 on there with the same wheel. Power still seems to be flattening out...actually dropping off when vtec kicks in.

secondly, Does anyone know the procedure for clipping a turbo? I am familiar of the basics of it, but which part of the turbine wheel are you actually shaving off??

finally, What is involved with a major tune up? I have put about 100K km on my engine and I am due for some major maintenence, what things do I need to change? Oil pump, water pump etc.

plugs wires, valve adjustment, compression check. Ever done a timing belt? can't hurt. Could do water pummp at the same time too.

Power dropping off up top....
Curious as to what your full set up is?
Does it do anything else weird?
