you drilled thru the headlight lenses? good luck with water intrusion and getting the lights to last very long. don't ask for a warranty fix because they will laugh at you.
There's your problem. You believe anything a tech (even a
SENIOR one) would tell you at a dealership? About as honest (or knowledgable) as the salesmen. All of my friends S650 sensors are always within 1 LB of accurate. That's all they are supposed to be. To alert you to a way underinflated tire.
good luck in your hunt. don't hold your breath for a Mach 4 or any signigicant changes coming to the S650. What you see is pretty much what you will get.
Not much different from MANY Hellcat owners turning 13's. One thing they have in common with the Supra drivers is they need the driver mod. I love racing most Hellcats. My 12.0 Scat Pack beats most of them by 10 car lengths.
bought a used car and believed the dealer about trading for a Dark Horse? already been to a body shop for repairs? Get out while you can. It's only going to be worse going forward. Buy a new one next time.
you can continue to forecast what you see as the way forward, but it will never happen in our lifetime. small changes are all we will see till the end of the gas engines. Sure there will be future performance upgrages, but at a higher cost and probably more weight. might as well ask for a 3000lb...
