Also, the TC is too intrusive to use with boost. A fancier system like on later cars can work pretty well, or an aftermarket one like RaceLogic works well in daily driving.
I just removed the throttle butterfly on mine. Didn't really feel like buying a new silicone elbow.
I demand reparations for confusing my junk. I get hard every time I skim past the thread title and see "993 TT Stg2 build"
Still some logging @ 13-14psi
Does the fuel pressure (User2) look right?

^This. Finally got my innovative wideband working but the tuning world seems to be stuck in the early 2000s. I need to use a damn USB converter for the RS232 port just to hook it up to my computer. But windows 8 still doesn't recognize the software. May just need to hop on the dyno.

This Zeitronix option helps alot with doing datalogging on the fly.
I swapped from the two port to the one port eboost2 config in hopes of fixing my boost spikes. But it doesn't look like it helps since I'm still experiencing spikes
so far I've done the following with no success:
-Swapped 6psi wg spring to 10psi wg
-Changed from 2 port to 1 port eboost2 config along with stainless steel wg lines
-Lowering gate pressure on eboost2

Almost seems like the current wastegate (Tial F38) can't seem to control boost above 12psi no matter the gp setting I use
So I decided to swap out the 38mm wastegate that was included w/ the TT Stg 2 kit over to a Tial MVR 44mm wastegate. Previously, I mistakenly assumed the 38mm wg I had was a tial f38.
Results looks promising so far after limited testing, no spikes even with the higher gate pressure setting
With the 0.8bar/11.6psi spring, I am getting ~13psi on my eboost with SP=0

Made some more minor changes..
Swapped out the old air filter to a vibrant air filter w/ bellmouth
Swapped out the Forge BOV to a Tial Q BOV w/ brown spring
Seems like drivability has improved w/ the Tial bov
Deleted the ASC w/ Maxpsi TB boot
Did some more testing evaluating the Tial MVR wg
Looks like I can start playing w/ the boost setting now that it's much more stable

Nice...I guess boost spikes aren't normal after all.

My boost was more stable after shortening the eboost2 solenoid lines. I moved it from the passenger side of the car to under the car at the center rear of the x-pipe.
