This problem (or not) that I'm seeing is a constant thing. At WOT in lower gears, 1st and 2nd, boost spikes to about 19psi then rapidly drops to about 13-14psi then I'm ready to shift. At the higher gears when I do this the boost holds better, maybe only dropping off a couple of psi from 19 to 17psi.
I'm thinking that maybe this is normal for a Giac tune that I have from Awe. Other mods are: Autobahn hose kit w/Tbb, Bailey DV's, Awe catback, K&N airfilter with modded air box and MBC.
Also I recently changed the fuel filter and always 91-93 octane. This week I am doing a boost leak test.

 

Sounds like normal boosting to me. You'll generally spike around 19 and drop a bit in the first couple gears, and sustain a higher boost in higher gears. I wouldn't worry about it, but there is no harm in doing a boost leak test every once and a while :-).

 

sounds normal, these K03's are WAY out of their efficiency @ 19 psi and 5000+ rpms...

 

That's what I was thinking. Thanks for the input guys!
