Hi Guys,
I guess I'll start with a power mod list, it's not too extensive.

Kinugawa T518Z-16G w/PTP Lava Turbo Blanket
DW 750CC injectors
Grimmspeed 3-port EBCS
GMS Turbo Inlet
K&N Typhoon
NGK One Step Colder coppers
Walbro 255
Other assorted bits (GS crank pulley, etc)

I installed the final mods 2 weekends ago, got the car running and am now tuning. My boost has a bit of a "wave" to it. I've been reducing TD as I feel that the EBCS is being allowed to overcorrect too much, but I wanted some input. Here's a pull from last night, the boost is only fluctuating .5 psi but you can definitely feel the back and forth. Target boost for most of this pull is 20PSI:

(ignore the A/F Sensor reading, I am tuning using AEM UEGO not listed in this log)

I'm thinking I still just need to tone down TD but wanted some input. Thanks guys!

Edit: trimming TD incrementally seems to be smoothing it out, also adjusting wgdc to reduce error.
