The more i looked at it I agree the 1/8 mile seems off, whether its the sensor or what the case is..that would make the most sense of anything. I do shift fast, even faster than most guys with dogboxes and such, but that doesn't like you were saying wouldn't equate to 1/2 sec over your 1/8 mile. I'd like to get it out to the track again to see if maybe the 1/8 mile sensor was off, but the track is closed out here now.
The tuning was done by me, its actually a tuned 04 STi map that I use for a starter on most cars, but it loved the map, so almost no changes were needed. I'd have to go back and look at logs to give you the details on IDC and all the other goodies.
the car is full interior, like I said above w/ one of my Open Source tunes on the car...maybe the secret to the speed is the WRX intercooler
