I also have the grimmspeed TGV Deletes. I can't compare them on my car to not on my car. But I do think they help on the top end for us big turbo guys. Grimmspeed makes nice products and you can send in your core. I paid the full then send in my core and they gave me back the core fee. It was like 140bucks. I don't regret buying them.
How long have you had yours installed? I suppose the butt dyno doesn't show much of a performance gain, huh? My turbo is small, bro.. it physically looks stock, so no big turbo here..
I know island78 just got his.. and he loves it!

I had them since the last tune. I think you wouldn't feel the power till the higher rpms. But yeah when I got them I installed them the same time as my GT30R. So don't know if it made a differents. But Grimmspeed says that it help the torque on the down low on a stock turbo. Try look on NASIOC and search TGV Deletes. There are alot of guys that swear they do make a differents.

Dang.. I'm SUPER confused now!
One side claims to see a difference at the top end only, and the other side (in this case, Grimmspeed) says you get better performance down low.
Who is right? Both?
Does it mean that a larger turbo will have the TGVs perform better at the top end and a smaller turbo the bottom end?
Gaah!
Sorry for the noob questions, if this is boring info to you...

I would believe by putting in the TGV Deletes that it will cause less restriction in intake manifold cause better air flow. With a good tune you would see some nice gains with them.

I will be having TGV deletes installed soon and we'll see how much better it performs at the coming ProTune!
Just picked up a pair of Prodrive specific mufflers for the tune as well....

Most power gains on a stock turbo can be seen in the entire powerband, however when you upgrade to a larger turbo gains are prominent up top.
