Hi, sorry for old question but i´m not find these question in FORUMS.My car is BPU and has Profec B, 13 PSI LOW and 17 PSI HI, Greddy BCC, FULL Downpipe and Cat back system and ICE BOX with hi flow air filter.What the best way to run a daily car and track car ? Is TTC or Sequencial ? The car has more HP with TTC ?

Thank You.

Have you seen this on MKIV.com ? http://www.mkiv.com/main/index.html
I doubt whether you'll see any difference in say a standing quarter. When I did this (the temporary way) I noticed a slightly smoother delivery of power with a noticeable reduction in that huge surge you get normally at about 4K when the second turbo kicks in. I did not get any increased turbo lag at low rpms. I prefer the power delivery of the stock sequential set-up. It just feels more sensational.

Ok, Sorry for delay. But, thank You very much!
