With the tune on I get LOWER performance readings than with the tune on.
Would you be able to test it also?

I need to get my VBOX back and confirm this. Dyno is one thing, but real world performance is where it counts. I'll test 0 to 60, 0 to 100 and 60 to 130 before and after. I'll use full auto mode to minimize human error.
And for all those truck vs SAV/SUV folks, have you not heard of a euphemism? Jeesh. Was just making a point. I've had 11 BMWs in the last 20 years so I'm aware of the specifics of each platform. Just trying to draw a descriptive contrast between a 3300lbs sports car and a 5200lbs SAV...
