downshifting to achieve fuel cut

[theholycow]

I agree with the ok-to-shift crowd, as far as GM (and probably Ford) vehicles are concerned. GM transmissions are happy and healthy under any treatment I give them.

However, DFCO is tough to get in my 2002 model with the 5.3 V8. I have to be off the gas pedal and higher than 1500rpm for more than 6 seconds before it cuts the fuel. It will then stay in fuel cut down to ~1100rpm.
