You are getting false information. 2 or 3 degree Timing key will get 2-3 HP gain. Also remember when adding more timing you must ran higher octane fuel.

Offset key/timing key same thing. If an EFI sled 3 deg may be a bit much on 91-93 octane fuel....but if you in fact run 98 you should be good.

You're bound for trouble if you go with a 3 degree key on an efi sled. Guaranteed!!! And yes even with the high octane fuel. This all speaking from experience.

I disagree that your bound for trouble with a 3 deg key. I have had them on 3 firecats, the latest has a y pipe, pipe mod, v force reeds and air box valves all with stock fuel system. 4600 miles with no trouble I always run 92-93 octane, a few times it wasn't available and I ran 87 octane and took it easy on the throttle with no issues. Cheapest improvement you can make that you can actually notice IMO.
