Would you notice any power increase if you ran the car with 94 Octane instead of just using 92? Or do you have to get the TS ECU flash before you can take advantage of the higher octane fuel?

 

when MA had the 94..I didn't notice a huge diff...but only "mod" I have is the K&N drop in...

 

With your mods you might notice a difference with an extra point or two of octane increase. With the reflash, you tell them your mods and what fuel you are using, and they adjust the ECU to meet those parameters.
