DFCO Disable

Has anyone here had their tuner remove all of the DFCO from their tune?

Here in Seattle I spend a lot of time coasting in gear down hill and the popping is getting to be a bit much. Livernois can drop the table for me, but they can't make any promises about the outcome.

I can't see any downside beside the obvious fuel economy impact, but would love to hear other's experiences.

TIA

LOL! Yeah, I hear you. I wish I could make it have a dual personality like I do with my truck, but since I can't, I'm going to have to move towards the less poppy side.

I didn't mind too much until I put the Corsa exhaust on, but it amplifies the issue.

**** - I really am getting old.

When I first got my supercharger installed, it dialed up the pops and farts by double or triple. While fine and entertaining on flat ground, but it got annoying descending thousands of feet down highway passes. i.e. the car is mostly in decel for 5 minutes straight and speed is managed with gears. It also hurt the sleeper value of the car. I had my tuner dial it back to around the stock level. So it still pops and farts some on decel like a stock SS. I don't know how they achieved it and for fuel economy, I don't drive my car on a regular commute, so I can't determine any impact.

Real muscle cars do, as evidenced by our cars (among MANY others) doing it.

Just because it didn't do it in the past because the manufacturers didn't give a **** about economy or the environment doesn't count.
