Decided to pull the superchip, replace the octane bar

Decided to pull the superchip, replace the octane bar

--------------------------------------------------------------------------------

I will set the timing at 14* in my speed density 87 stang.

Will I feel a gain or a loss or do you think it will feel the same??

I have a full exhaust and 65mm TB with a K&N air filter. Do these chips work without mass air anyway??

I've had it in 12 years or so, but the exhaust is new...
