A little update on this file... I was playing with it today and demonstrating the anti-lag to a friend of mine. Seems the pinging is gone (probably just carbon deposits due to my lack of a catch can on this car) and it will hold 10psi, but, immediately after two 2-3 second demonstrations the car went into soft limp and wouldn't boost past 6psi. I figured I blew up my ancient N75 or split a hose, but everything under the hood checked out. Cleared the codes and we're back at 23psi.
I had this issue last night at the track. If I would engage antilag, but then let off, and go back on then try to launch, it would bog and only boost to 5-6psi in first, and 2nd, but then 3rd and 4th it would boost to 20-21ish.
However, it worked fine when I engaged antilag, slipped the clutch, without letting off the throttle. I wonder what it is? I scanned for codes with vcds right after the first run that did it and there wasn't anthing.
FWIW: The best run last night was a 13.17 at 105.47 with a 1.87 60'. There's a lot left in it. I think I might bump the launch RPM to 4000 and try out NLS on the 3rd to 4th shift.
EDIT - After looking through the AL/NLS section of the tuning wiki, I noticed it said that some "features" such as Disabling Misfire and Knock detection (during AL/NLS) could be missing from the code.. Possibly causing a DTC/Limp or Pulled timing. I'll definitely log my next 1/4 mile runs.
