Edit: I've seen this in another thread:

I tuned out my decel popping this morning. Worked great - NO MORE POPPING/BURBLING/GARGLING! The problem is with the DFCO feature (Deceleration Fuel Cutoff). You can disable it by modifying parameters (like engine coolant enable temperature, enable RPM) such that it will never see those conditions (480 degrees F, 8000 RPM).

Disabling DFCO isn't the BEST way to do it, (the best way involves a LOT more trial & error work) but it definitely shuts it up.

I could be wrong because I never use the User Adjustable Features of the Predator since I am a CMR Tuner I always do all my adjustments through the CMR software, BUT

I don't think you can turn of Decel Fuel Cut Off through the user adjustable Features.

I believe you have to have a CMR Tuner Dealer Do it for you.

After you install the Predator you will have to extract the original backup and the last tune written from the Predator, and send them to me Via email, I can then tune out DFCO.

Ted:

In your expert opinion, is there much more performance to be gained from a custom tune for me? I have a Corsa cat back system, and a CAI Inc cold air intake. I installed the "performance tune" - what the Diablo called it. Power is noticeably better. Could I get even better performance with your tune? Or would you need to see my specs (not sure what you call it) before knowing if more power is there to be had?

Only If we put it on the Dyno we could find that last 10-20% of available power.

The tunes that come in the Predator are Good for What you have, if you get in to Heads and cams, Headers or superchargers then those tunes would be Useless.
