Going back to NA from FI

[16902]

So, anyone having done this please give me some input.

I have just removed a turbo system from my P5 and will be returning to NA. All of this time (about 4 years), I have been running 93 octane. Should I be able to just back off 93 and go to 87 cold turkey?

It seems like an easy "yes" but I thought I should check. Thanks for any input.

It should not be a problem, you were running 93 cause of boosting. Since the car is going back to stock unless your ecu is not stock it wont be any problems.

Thanks. I wouldn't think so but I figure it is always a good idea to ask others.
