I have been experimenting with my '96 F250 Powerstroke. Apples to Oranges here. Allegedly, the less boost pressure, the better fuel economy. Personally, I'm watching my EGT gauge and keeping it lower than 600 degrees on acceleration from a stop. This sorta emulates what I am doing with the 99 Chevy Metro 3/5 n/a.

Pulse and Glide? My F250 is an automatic. So I have tested the "glide" (in neutral) to see how long it takes to glide from 55 to 40. Then I do the acceleration such that it is about 1/2 the distance to get to 55 as it does gliding back down to 40. Example, if gliding 55-40 is 20 seconds, then acceleration is 10 seconds. This gives me about 5 psi boost, where max boost is 23 psi. Experimenting in progress...

There prolly ain't too many turbo gassers around, so you'll likely be in new ground on your results. Experiment A LOT and hopefully you have a scanguage or similiar to check your results.
