Hey guys,
I've been working with my tuner since the beginning of the year, but can't seem to dial in the tune. Every time he brings the boost up, I keep getting WGDC dips around 5500-6k and boost seems to drop. I'm fairly confident it isn't the tune as he's got a lot of experience with the gc.
Would anyone know what might be causing the issue?
No loose clams or intake leaks, compression test passed, no cel.

UPDATE:
So it turns out it was tune related even though the previous tuner had me convinced it was something mechanical with my car.
I switched tuners and now working with OdinTuned and am extremely happy with the results on the first few revisions. Not sure why the previous tuner was having trouble, but I definitely recommend OdinTuned for anyone looking. Great communication, fast turn around and even gives you a breakdown of what he adjusts. No hard feelings against the previous tuner, but definitely looking forward to the next revisions from Kirill!
Experience with Vargas:
I do want to add for anyone looking at any Vargas product to STAY AWAY AT ALL COSTS. Even though I'm happy with how the turbo performs now, their customer service is beyond horrendous. I can confirm first hand that all the negative reviews and comments are true and the only reason we don't see more, is that they actively remove or suppress anything negative whenever possible (probably why most of their products have no ratings). They are quick to blame the customer and will not take any responsibility whatsoever, just read their responses to anything critical.
It's unfortunate because I wanted to like and use their products, but never again. I hope this helps anyone considering and If you do decide to purchase from them, good luck!
Update Part 2: Final Logs from OdinTuned
Just want to share my final logs. I'm very happy with how the car is performing now and can't recommend Odin enough, thank you again!
