I would say put in 91 and tell them you want the car tuned to run the higher octane. That is assuming you want to get better HP, not better mileage.

when u get tuned they will tell you what you need to run . if they are leaning out your air fuel ratios and timming then you will prob need to at least run 91. you should be running at least 92 with the maf kit you have. i have the same thing. and C&L recomends running 92 to prevent any possable detonation.

pre-ignition of fuel/air mixture in an engine (before the spark plug lights) due to high pressure or high temperatures. Low octane fuels have more of a tendancy to detonate. Usually occurs in the combustion chamber...at least you better hope it does.
