hello everyone :) im new here.

hey guys ive done sm research nd im so confused! i have one question:
how does a dinan chip compare to a markD chip??
does anybody have a link for dinan chips(they seem much cheaper).
we have 95 and 98 octane fuel!! how will these chips work?

your octane measurement systems are a bit different than in the US. 98 is apparently about equal to 92/93 in the US. And for a chip, you want Mark D. His are as good as it gets for an M42.

you need to use the search tool. There are tons of threads asking this same question. And you don't need a dual exhaust on an M42. you won't be able to tell a difference aside from the placebo effect from the sound except maybe for a different muffler.
