Anybody notice high RPM or heavy load at low RPM improvement from an aftermarket coil? If so, what brand/model?

Thanks.

I can't say for the LT1 for sure but I ran one of the Hypertech coils on my 91 454SS pickup and it made a big difference throughout the rpm range. It really smoothed out the idle too. And if you're looking for one, I have a brand new Hypertech 4055 coil for the LT1 sitting in a box. $55 shipped.
