Apples n oranges... At issue is bogging upon acceleration. The occasional stalling on de-cel has a different set of circumstances and characteristics; perhaps coincidental to secondary delete and Marc's calibration. But, it is certainly NOT a new phenomenon, and NOT exclusive to the LT5 at all.

And, with regard to deleting the secondaries, in many cases, it is often in conjunction with some amount of porting; porting which alters the AF requirements a bit which may well "poke the bear" a bit.

So, IMO it would be a mistake at this time to make attempt to codify a connection between the secondary port throttle (SPT) elimination OR Marc' calibrations exclusively (others do both as well). Juuuust sayin.
