WHY, flying tachs excite you? You can probably add a frequency multiplier to the tach, multiply by 2 should do it.
best modifications for throttle response?

That tach is just an indicator. I've always loves engines that seemed perfectly matched to the position of the accelerator pedal no matter how fast it moved. At car shows, i could see cars that would ramp up from idle to 5000 rpm in a snap and back down just as fast. I'm pretty sure it's mostly the result of higher compression engines, but it seems to provide a more solid connection between man and machine.

Get a tiny engined car then like the S2000 Honda or Rotary Mazda-rev it to 9K-doesn't DO much but make noise. I'll take torque and low rpm's anyday. Engines with big pistons and lots of moving mass don't do this well. If you look at the European cars that can, they have tiny pistons (like Ferrari).
ever hear a top fuel or funny car rev?

Our electronic throttle doesn't help. I think they are programmed to not deliver 100% power in the first 20% of throttle travel. Or something like that. It's probably for engine reliability. I still prefer conventional throttle cable. But, almost all cars are drive by wire now.

Yep. Same for motorcycle (smaller displacement) engines. Basic physics. It's not so much how high they rev, but how quickly they get there. I'm with you. I'll takes my torque every time.

I don't give a flip what my tach needle is doing or how cool my exhaust sounds. I care about getting pushed back in my seat and the illusion that the road has suddenly become very narrow.

I dont see why you cant have an engine that will rev really quick and yet still have a good low end. It seems like to me that you would want your engine to do that especially for road racing and for rev matching, plus the less rotating mass there is the faster your car will accelerate...

NOPE,, coils will give you NOTHING over what the OEM coils provide, There NOT a weak link in the C5. Neither are wires or plugs. NO performance to be had there!
What you need is TUNING. Specifically, the throttle response tables. Not everyone has the correct knowlwdge to alter them correctly. If you do it wrong you destroy the PCM and TAC modules! $$$$$$$$$$$$
lionelhutz Hit the nail on the head. There are changes that can be done to the throttle files. Give Chuck at Corvette Of Westchester a call. If theres anyone who knows the in and outs of GM PCM throttle files, its HIM.
I'm positive he can mail order tune your PCM to get you what you desire!
Talk to him and see if he can provide you what you desire.
