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.

 

Simon, take a ride in Jimi's scooby. If Im not mistaken, he has it on already.

 

Will do! Thanks for the heads up, Walt!

Hope you're doin' well, bro.

You've been MIA on my neck o' the woods!

 

Thanks, zer0shift!

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.
