any difference in fuel economy from 91 to 87?

Curious, why did you want a map for 87, and 91?

[phoreal]

87 is cheaper then 91

hmmm.....how many miles before you see your return on investment?

+1

assuming you save $.20 per gallon that would be roughly $2 per tank. if the tune was $500 that is going to take 250 tanks of fuel to pay for itself and thats if the 87 achieves the same mpg as the 91.

[kandyredcoi]

assuming 91 is $3.30($3,013) and 87 is $3.10($2,830) and you drive the avg of 15K miles per year @ 230miles per tank, you would save approx: $183.00

is it worth the power loss etc. ???

For this particular guy, the company pays for 87 so it is free. The additional tune for 87 octane was $130. He switches with the cruise control button ($30 goes to Tephra).

The 2nd toon pays for its self after about 2 tank fulls :-)

He'll prolly get better mileage on the 87 tune since there is less reason to mash the gas pedal to the floor.


Taaa-daaa

Power loss is negligible and since 87 is free for him then its an no brainer

Nice work
