First things first , you don't know **** more than I do but you're certainly free to think you do.
You're right, it's about "lag in the throttle" or "hesitation" which you say is built in. I say that's a bunch of bullshit.
I've never said the Sprint Booster doesn't work and I'm sure people that have it like it.
You have modified SRT's, I have a stock Limited, you'd win any drag race easily. Or you should.
On a road course you should win also. Probably not though. I doubt you possess the skill set or have any experience at such a venue.
The performance driving season is pretty much over for this year in the northern states. Even good summer tires are not designed to work below 40F, though I'm sure you knew that. The daytime high here yesterday was 48F. Though I have done some open track events (on lucky sunny days) in October in years past. I'd be more than happy to show up at an open track day event next season to see you scratching your head trying to figure out how a Limited could go around a road course faster than an SRT. Have a good day.
