Anyone got the Black Bear AutoCal kit?

If 93 octane were no more than $0.60 over 87, I'd still use 91 or 93.
But since 91 can be as much as $1.30 over 87 in NYC ...

I was talking to a Tuner about tuning the Yuke to 89 Octane. In my head I am thinking it will get improved HP and gas will still be semi affordable.
At a Kroger in Fort Worth, Tx.
87 oct is $2.89
89 oct is $3.14 so $.25 higher
91 oct is $3.44 so $.55 higher

It's worth talking to him about it!

At those prices I'd tune be tempted to tune for 91 octane.
In TX I very much doubt that the price of 91 would run away from 87, like it does in NY.

With proper realtime calibration based on accurate feedback, 89 or 91 can be tuned for better power AND MpG.
In NYC, however, tuning for 91 will never recoup the investment due to the distorted 'premium'.
