Huh??? Not really sure what you mean. I didn't have the car tuned, and i don't have a boost gauge or anything. (yet)

As for the spike...i can't explain that either.

turbos are setup in sequential. 1 spools before the other at factory set rpms/load. the drop followed by the spike is the transition from 1 turbo to 2. boost pattern factory is 10 psi, 8 psi at transition the back up to 10 psi with in seconds.

It looks like the switchover is a bit laggy...Years ago i got a real good working selenoid and the switchover was way smoother. It still showed just not that pronnounced.
Almost 20hp over the average bone stock #s! I didnt read your mods list but i'm more than sure youre still running that pre-cat? Ditch it and get a dowpipe, it will net your a few horses and improve the switchover a little! Anything over that and youre asking for trouble! Be careful when it gets cold! you'll need a rechiped or piggy back...if you got the sickness a stand alone will go a long way!!!!
how many miles on the motor/trubos???

Yeah, it's got a 3" downpipe all the way, with the cat still in place for the emissions test.

New motor--5,000miles ago from the previous owner. Not sure about the turbos.

I'm not that worried about it anway, i've got stuff on order to make it run better, including an eventual single turbo, and FMIC. (etc.....)

good! just keep up with maintenance and you'll be fine! you'll get a kick once you mod it a little more...and a single, forget it!!! lol
