It seems to have taken forever, but I finally nailed my launch last night at the dragstrip. So far, the car is nearly stock. I did the upper pulled a couple of weeks ago, and a set of K&N filters on Wednesday. As it got cooler later in the evening, my times actually got worse. I went from a solid hook off of the line to having no traction whatsoever for the first 80' or so.

In any case, this was my best run so far and I thought I'd share it.

What was the timeslip? How did you get that video with heads up display in it? Great video! Add the ECUTG tune and You'll fly. Looks like your boost level is still same as stock cause without a tune it just bleeds off by the ecu. Stock XFR boost 10.2 psi, and XF S/C is 7.3psi.

 

The timeslip was:

60': 1.972
330': 5.427
1/8: 8.219 @ 89.04
1000': 10.595
1/4: 12.602 @ 112.67

The boost levels are actually affected by the elevation. The track is at about 5100' above sea level, so cars in Denver tend to run a bit slower than at sea level. I intend to get it tuned, but I'm not interested in a mail order tune. All of the tuners seem to reside at or about sea level, and I'd like to not leave anything on the table, performance-wise. Unfortunately, Denver is a barren wasteland of Jag tuners.

 

The heads up display is an Android app called Torque. Best $5 I've ever spent.

 

Damn, impressive run! I should be back out there September 12th; hopefully it will be even cooler out by then. IIRC, Bandimere is actually 5800 ft. above sea level.
