Default 07 vs 08 drivability mannerisms (DFCO)

Do the 2008+ bikes shut fuel off completely anytime you let off the throttle above 20mph?

Even after a year and a half, this makes my 2007 still really annoying and makes the bike sound like shit on deceleration. I talked to Lloyd about turning off the DFCO, but he said they don't mess with that map because of high idling issues.

Install a map from an 05 Hammer. 08 is prolly the worst year for Victory drivability

I'm not an asshole...I just type that way

Why is the 08 drivability the worst? Mine seems to want to stall or sputter sometimes while other times its fine.

2008 Hammer S - Cams, TTi, PCV, adjustable timing, Thor exhaust

I edited my original post to be more clear. I hate this characteristic of my 2007, and I'm wondering if the 2008+ bikes do it as well.

05 Hammer did not have cats in it, and so they did not need the fuel cut strategy; to keep them clean. Gets rid of the wandering missfire at idle, and the cracking on shifts, decell, etc

For 08 Vic was a tad behind the learning curve, and the bikes had some built in drivability problems. The issues got better each year, and by 2010 they had a much better handle on things. Still some bugs, but they are asking a fairly stupid ECM to do some advanced things

Neither did my 07. I have an autotuner anyway. The Deceleration Fuel Cut Off is the only thing I'm wondering about for newer models versus 07 and older.

2007 Hammer, lowered, Bassani 2:1(updated), torque tubes, Dobeck AFR+.
2000 Firebird Formula, 6.0L, LS3 heads, etc, etc, etc, - SOLD
HM3(FMF) - 3/7 Lima Co. 2010 Helmand, Afghanistan

All 06 and up Vics had cats in them from the factory. So yes your 07 had them; even if they were later removed. The 05 Hammer was the only 100" that came from the factory without cats. So it does not have fhe fuel cut stratagy. I'm not talking about changing the map in your PCV. I'm talking about reflashing the underlying stock map in the ECM.
As for 08 and later. Not only do they have fuel cut, but they also have an IAC that kicks wide open on chop throttle. Again to assist in cleaning the cats. A closed loop Vic with loud pipes will set off stray pops that sound like a drive by in progress
