I'll do that today and see what I can get out of it

But, if it goes missing any time soon, I'll know where to look

I do wonder, though, if I get a blower soon, should I be able to blow off all the stock 2011 GTs out there, at least at this altitude?

Yeah just switch to the next size pulley to make up for the PSI you're losing at this altitude and go beat up on all the modded N/A guys

Just to reiterate, look how much HP you're going to gain by shifting later. Consider this a manual tune that you apply directly with your feet and arm. I'll take check or MO for $250.

My schedule keeps changing, but on my way home (currently in Buffalo, NY) I'm going to do second gears pulls with the G-Tech here, at 3000 and 6000 feet and I can put them all on the same graph for comparison.

On the way here I noticed that climbing a hill there would be at zero vacuum or just into boost, where when I got to the other side of Kansas I could climb a similar hill, with similar acceleration, at 10" vacuum. The difference in oxygen content at 6000 feet is about 30% less than sea level. That's a pretty serious difference.

My house is at 9000 feet, so I feel it quite a bit.
