I have recently made the switch to TQ fuels,I used to run tornado(25%) and nitrotane(30%).The switch was seamless.The quality of TQ fuel is top notch,I never even had too turn a needle to adjust for anything(still check your temps).Temp rite where it is supposed to be and the power was great.So anyone thinking about trying it,stop thinking and give it a try you will be more than happy with your choice.As a plus the guys are great to deal with,that goes a long way now a days.
