So, I installed the Buschur TB seals this weekend! I have to say it is a really easy procedure. Took me about 45 minutes and I wish I should have done this alot sooner. My evo spools up about 200 RPM's sooner and I have to use less throttle pressure to pic up speed. Of course I did a leak down test to confirm the Seals worked properly. (33 PSI's and no leaks anywhere) I really recommend this to anyone who has a leaky TB. Hope this helps in convincing anyone about doing it.
