I will concede that in terms of cost benifit ratio 20psi to get 83hp gives a feeling of something lacking.
Having said that; in your mustang community how many people with forced induction (turbo kit or supercharged) run 87 octane?
No one as that is just stupid....93 or above unless you are in CA where the max octane you can get is 91.
I understand why Ford has done this as they did it before on the 03/04 Cobra's to protect people from themselves as it has been proven time and time again how effin stupid people can be...have a 390hp car that clearly states 93 octane only yet Ford had to take into account the idiot who would put 87 in it, hop in the car and run 120 uphill in 5th gear.
I know people are impressed with the tune on the ST's but a lot of that is with using 93 octane which means you can add more timing which means a lot more power esp on a FI car.
