Question Turbo Port and Polish ?

LIC Motorsports in Navato has a P&P for turbos and I was wondering if anyone had done this, or seen results on how much it gives you.

FYI I am thinking of doing this to a VF-34 that I have set to go on my car.

Thanks

I had my vf22 p&p at Lic and when i got tuned the tuner said it was much easier to control the boost b/c of the ported wastgate. As for power gains i cant tell you b/c I didn't do any before and after tests. I can only assume that if you can control the boost better than then you should be able to control and fine tune a little more. I also know that it helps with spool up and boost creap, epecially if you have a 3in tbe without a cat. If I had to do it again and spend the money I would. I feel that it helps tune for the turbo better and helps the effeciency of the turbo. Oh yeah, I would recomend getting it done at Lic. They are great!!
