So I took em off and replaced them with somelonger ones that bent in such with out squeeziing the air off. I then proceeded to make my boost controller nipples a bit larger becasue I wasn't able to let enough air pass through last time around to get the primary turbo down to 10 psi. After a couple of test drives I adjusted my valves to a pervfect 10 -9-10 pattern. When I shift the PSI now keeps at 10 psi with the second turbo.
Hehe, I knew it was either a problem with the lines going to the TCA/TCS! Anyways, I am glad you solved it. Doesn't a 10-8-10 boost pattern feel nice?
