Analyze my 1/4 mile times?

Hi all,
So I picked up a Dragy to do some testing and finally got a couple 1/4 runs down.

Car mods:
  • JB4 on map 5
  • CTS Turbo Intake/FMIC/Charge Pipe
  • 3.5-7 gallons of e85
  • Stock run flats, stock downpipe

I'm still working on the launch as getting traction is a struggle. I've found brake boosting to about 2k in sport+ (sport automatic shifting) and massaging the throttle in 1st and 2nd gear gets me a 0-60 time between 4.88 - 4.92s pretty consistently (4 tries)

I changed the max boost in first gear to 12PSI on the JB4 as with it not set, it was very difficult to maintain traction.

I'm really enjoying learning how to launch and test the car out. I'm wondering what you'll think about my times, are they about where they should be considering my mods and conditions, I want to make sure I'm learning the correct way.

Pull 1:
  • 60ft: 2.24s @ 32.17
  • 330ft: 5.73s @ 69.86
  • 1/8: 8.55 @ 88.37
  • 1/4: 13.06 @ 107.22

Pull 2:
  • 60ft: 2.19s @ 32.16
  • 330ft: 5.70s @ 69.37
  • 1/8: 8.54 @ 88.37
  • 1/4: 13.09 @ 100.23

Thanks all!
