MarkD Chip vs Miller MAF w/ Basic Chip

[EatsHondas]

So Digger, about that 91 octane chip, can I run 93 octane gas with it? I don't have access to 91. The common options for me are 87, 89, and 93.

I used the miller maf with chip programmed for 19lb injectors and free flow exhaust. They told me if I wanted to come up to aldergrover and they would tune for free. Engine was 95k with 190 compression across. I feel it made a substantial improvement over stock. You can get whatever you want but others here have there opinion and it doesnt mean thats the way. Do what you feel best.

yeah you can use 93 with a 91 chip but you wont make any more power but they say the higher octane fuels keep the fuel system cleaner so no real harm maybe a bit extra $$ per tank
