You won't notice much of a difference with a cai without the custom tune. The programmer is hands down worth it! Especially if you ever plan on changing the tire size. Also look at the php forum you may be able to get a used gryphon for a good price.

Okay good. I was surprised too, how much better it ran with the custom tune.
Wish I could afford to run the 91 Cai, unfortunately I just can't resist stomping on that damn pedal.

No. You need to upgrade your old edge at PHP's website to a "gryphon" then have bill write you a custom tune with a specific octane choice...

You will love what a custom tune will do for your truck.. Fords factory tunes are a one size fits all tune that caters to the broad range of customers.. A custom tune is tailored to you..
