When I had my ECU flashed from Al I specified that I was using 91 octane. I made a mistake in that because we actually use 93 octane. Would that cause any loss of performance or cause the engine to not operate at its full potential that would warrant another reflash or am I just pissing in the wind?

 

I would think so.. that is a pretty significant difference we're talking about. Im sure the other more experienced memebers will chime in.

 

a reflash would be in order to maximize the potential of the car

higher octane gas enables you to run more boost with less occurrence of knock

you'll be fine driving the car the way it is but I would assume your a/f with the two gases would be a bit different...if you can afford it get the reflash

if not your car will be fine just not as powerful as it could be

what psi do you currently run?

 

I run the car at full boost hitting around 22 and tapers down to around 19. Off the top of your head what kind of performance am I missing due to this?
