S1 system will help promote a healthy curve as you go up in power/boost... but the current idle pressure spike you have is a side effect of the pump and the fix for that is unrelated to the RFS upgrade. The RFS will still run the venturi's so the venturi flow has to be opened up a little to fix that idle spike.

I'll admit I'm not absolutely sure what you are referring to being drilled. Do you offer an upgraded tube that wouldn't require drilling? The thought of doing something not reversible leaves me a little uneasy.
