With that many miles, do the Hearbeat. IMO, Callaway is appealing on new cars since you get the warranty.

heartbeat for sure, we do quite a few of them and sell a lot of them too. Always a quality product, the new direct drive is really nice for people who want to max the blower out down the road.

Callaway only does cars with up to 5,000 miles so you can get the factory backed warranty. That's why I got into a CPO car with ~165 miles on it. So in your case, get the Magnuson.

On Heartbeat, aside from $500, what's the calibration - non-calibration difference?

Having your car tuned with a canned tune vs a tuner doing one specifically for your car which costs probably $500.
