You have a c900 with FWD through a trans of questionable torque capability. Your engine is tuned to give a lot of low/midrange ooomph and not quite as much at the top end, a trait which is amplified by the tuning methods most people use. Under these circumstances, pray tell me why trading some of this low/midrange madness for high rpm flow is a bad thing.
I can only guess the customers that complain about a power loss in the lower rpm range using the 2.1 head/intake combo are the same that brag about 'taking an xxx off the line' and subsequently complain about having broken their transmissions x times. That, or the bigger head/intake combo is not matched by the state of tune of other components. Admittedly, this is not something you do until you're some way up the performance ante.
If you want to have big power in a c900 without the wheelspinning, torquesteering histrionics, you'll need to find it higher up the rpm band. If you're looking for big, lazy V8 power - you have the wrong car. You can change the engine, but not the basic properties of the car it's in.
Flow is everything. Running gobs of boost with any given turbocharger just means the rest of the engine cannot flow the air you are pumping into it, quick enough. From a certain point you are well advised to looking into any airflow gains you can get, even if it means losing a bit of air velocity at low load/low rpms. Throttle response is an entirely different matter - you can have razor sharp resonse with a torque curve that starts low and builds progrssively through the rpm band, and there's cars with a torque plateau that starts from just over idle, but still soft and sluggush response in transient conditions.
