HP gains with different tunes and CAI's...

[Jordan]

Hi

I just ordered a Predator and i just want to try and figure out what octane i should run. My car is bone stock with the exception of SLP LM's axel-back exhaust.

What HP/torque gains, and MPG gains will i see with the 87 octane tune?

What HP/torque gains, and MPG gains will i see with the 91 octane tune?

What HP/torque gains, and MPG gains will i see with the 93 octane tune?

I'm also condsidering adding the K&N aircharger CAI to my mustang with the 91 octane tune. What HP/torque gains could i see with this combo with 91?

Thanks alot. Jordan
