Yeah registered on my boost gauge and AP.
I was able to dial out the overboost by backing off my Wastegate actuator arm, but then the wastegate stays partly open and I can't hit target boost. Honestly I don't think my WGDC are tuned very well close to the boost threshold. My problem is 4th gear pulls at 3500rpm I get the major boost spike. Boost onset at 4k+ rpm is normalish.

So, fellow enthusiasts, I was scammed. The 18G I was sold isn't in fact an 18G. It's a 16G. In fact, the manufacturer is unknown. Hill admits that this makes the most sense. My turbo fully spools by 3500RPM: This should not happen with an 18G on a 2.0L. Furthermore, the 275whp is much more characteristic of the 16G. Given that I wanted a 16GXT to begin with, perhaps this isn't so bad. I'm a little bummed. I was hoping for the punch of the 18G, though maybe after the wedding I'll send it in to Blouch and have it rebuilt with the XT wheel.
My boost spike is due to the fact that Hill tuned the WGDC more aggressively down low thinking that it was an 18G and that i would not make full boost before 4000 RPM. Since the turbo isn't really an 18G, I'm making full boost much sooner than expected.

The turbo is a TD05H-18G. Blouch confirms it. HOWEVER, it is a custom 18G. Instead of using the TD06 housing with the 18G wheel like the standard 18G, it uses the TD05 housing. The result (when combined with PnP) is very fast spool at the expense of slightly less power up top. Still, Blouch says I should expect 330-340whp from this (with supporting mods).
Well, I ordered a GrimmSpeed MBC from Kronos. Hill and I decided it would be the best to move forward with a hybrid boost control scheme. I'm still boost spiking in 5th gear, since I am in higher-load cells at that speed. Changing the WGDC to dial out the boost spike will leave me with slower boost response in lower load cells (i.e. 2nd, 3rd gear). By switching to the hybrid boost control, I retain the dynamic boost control of the 3-port and also set the MBC to 21 PSI to eliminate the boost spike. Best of both worlds.

Pulled the plugs today and checked the gap. 0.035" on all four. Hill recommends 0.030" gap, so that might be where some of the power was hidden. Car feels much peppier on the road, but I'm not sure how it would fare on a dyno.
Also received my MBC today (thanks Kronos!). Looking forward to going with the hybrid boost control this week!

Prepping for Hybrid boost control.
I despise the AP Pro-tune. I could be tuning my own boost control, but instead I MUST rely on the tuner. DO NOT WANT!!!
