On 93 octane 7/11 pump gas, & with factory cats my2015 coyote mustang gt put down 756 whp & almost 600 lb of torque. Prior I had the whipple factory tune that made 641 whp. The results of the incredible staff & state of the art equipment has netted me 115 whp & get this 1-2 mpg increase. You operate an excellent business and will get all of my future work & many referrals. Thank you & God bless.
