What mods did they do to generate those figures.

Stock car + Software flash.

Power is at the wheels.

Very impressive!

I understand the top part of the chart are Hp and torque, but what do the Analog 1 figures represent?

So this are the figures for your own car or somebody else's car? How's the driveability since the flash?

This is our DCT test car it drives fantastic. The DCT software has been optimized to handle the midrange TQ. The lower figures are boost.

Got it -that's quite an increase in boost. So a software flash that gives you a turbo boost means the wastegates are electronically controlled. I guess I'm a little behind on my technology - LOL.

I was trying to figure out how you could get an increase like that by changing only the fuel mapping and timing (ignition and valves); even with double VANOS I thought it was a little far fetched, but it makes since now.

I should have figured that before after reading about the n54 turbo lag and software update issue.

Thanks for the explanation.
