Is there a chip that is tuned for 98 octane fuel.

yup miller War chip

The 8.8:1 stock M20B25 is not really knock limited so the extra few points won't do much.

This is a question on behalf on my friend. So he can run a 91 octane chip like tms.

98 octane RON or AKI?

[nando]

He's in OZ, so I'm guessing RON

a mark D 93/94 AKI chip should work fine

there is a rumor that they will be cutting back on 95RON here and having mainly E10 or 98 so getting the 98RON would be better thinking about it logically even though performance wise the MarkD 91 PON chip made more power than the MarkD 93PON on the dyno in a test i saw.

i would use 95RON chip and run it on 98
