Throttle body porting!

anyone tried chances with porting TB?

I've read over in Camaro's forums it's building good buzz, and reporting fair gains with the maros V6 of 10+rwhp!

There are quite a few G8s with ported TBs.

I talked to mace and they said quote: We've attempted to develop one in the past, however they're extremely difficult to manufacture therefore we won't be making them

Vmax confirmed 'll do porting for our V6 TB, like done for camaros.

Quoting Vmax:
" As far as we know the G8 has to run the part nr you sent me, the side mounted plug, because your computer will not read the throttle position information sent by an LLT throttle body. I have hand ported this type of TB. The LLT and G8 bodies are basically the same and the G8 responds to the same modification as the LLT 2010-2011 and LFX 2012".

$150 for the porting job+shipping (their price as with camaros). Basicly they'd need your TB to work with.
With camaro crowds since its more going item for Vmax, they would send you ported unit with core charge thats refunded to you when you send them your old TB. But for G8 I dont know how they'd sort it out in US.

Unfortuantly for my case, it'd be outright sale , including new OE body, coz international return shipping will be not visible.

As far as I could find, although LY7 & LLT V6s have similar throttle bodies, but seem they have different plugs!, and sure different OE part numbers of throttle bodies
G8 V6's TB: GM # 12615503 (new # replacing older ones)
Camaro V6 LLT's TB: GM # 12616194 (or figures in other order)
