Update:
I finally got my car to the shop to get some work done. We removed the 1st cat and fitted a 2.25" short downpipe to a 3" flex pipe that met with my 3" 2nd decat. Overall a very quick and simple job, just had to wait to get that flex pipe from another shop. I pulled the fuses for a quick reset for EFI 1 and 2 and gave it a good drive on the highway. I noticed right away first turbo spooled up nice and smooth and quite loud then when the second turbo went on it kicked my ass haha. I was seeing a high spike at around 17 almost 18 psi. It seems high but I think it is with our temps in my city. Right now we are at -34C. So when it warms up in a few months it should be quite fun. So far everything is running great and it's a lot of fun!
I also have a Rush Racing Antilag unit from http://www.rushracingdev.com heading my way in the mail, I'll make a post when I get that in about it.
Cheers!
