Vacuum gauge instead of Scangauge?

OK, thanks for the feedback on my WOT. Maybe I'll 1/2 or 3/4 it to the ceiling speed of my P&G routine. The car seems to vibrate more at high-gear WOT; maybe this is just a byproduct of the funky holes I drilled in my "pumpkin" muffler. I hope that thing rusts thru so I can replace it with a DynoMax, lol.

I think you're right about the "tension point"; I can kind of feel the throttle position sweet spot. It's a tradeoff between spending less time in Pulse and more time in Glide vs. trying not to run obscenely rich during Pulse.

Geez, you guys, all this P&G theory drives my undiagnosed OCD crazy when I test it out on the road and imagine everything that's happening inside the intake/cylinders. Lol.

Wow, I just looked at the SGII website. I didn't realize it had so many functions (pulling codes!) or was so easy to install! Looks like I'll have to save up my monthly spending "allowance".

No worries. It's always good to have a mention of that when discussing P&G techniques anyway, would hate for a lurker to see that, and think it's OK for him to P&G engine off in his automatic. Next thing you know he's on the side of the road cursing the site and considering buying a Hummer for revenge.
