I find in my UrQ, that if i just let up on the throttle about 3/4 of the 
way in between shifts, i have MUCH less turbo lag.  I believe this is 
because i then dont have the pressure spike that i would if i just shut 
the throttle at 13 psi.

Another thing to remmeber with a turbo car is that you cant throttle it 
like a NA car.  You have to ROLL on to the throttle, you cant just mash 
it.  Contrary to whatou might think, if you take your time getting on the 
throttle, it will actually be faster because you allow the exhaust pulses 
to spin the turbine up progressively.

Anotehr thing is MUCH freer flowing exhaust.  I was over at Tim 
Valencia's place, and while looking at our race car, we were getting 12 
psi of boost just by reving the engine.  Of course, that is a K26 (stock 
one), with a 3 inch downpipe, and 3.5 inch tubing coming out of the side 
of the car...man it sounds great....hehe...
