Well, Majhik, obviously there is no arguing that it's been done, but I will bet that a characteristic of engines that bit the dust is sequential with a midpipe and that sequential with a cat has less frequency of destruction.
I get no spike. I get a smooth as glass transition and my boost is steady at 17-18 at full throat on race gas. I attribute that to PFS tuning and at least somewhat to the backpressure a cat provides & I think it provides a margin of safety.
I am sort of "stuck" at 11.6-11.7 & I have decided to live with it.
In the hands of a better launcher (like Boost7s 1.48, 60 foot) the car probably has an 11.5 in it but I don't think there are substantial advantages to non-sequential without a midpipe and I think a midpipe requires a new computer, a new boost controller, and learning to live with a weaker low end.

i dont understand what the argument is anywhere past 4.5-5krmp, in both cases arent both turbos spooled then? they are both on after then so what difference does it make anywhere past that?

I second the seq. setup. Had problems with my seq a while back and with the help of many forum members and their dedication on trouble shooting the system, my problem was resolved. However, I do agree the stock rats nest is a nightmare. If emission is not a concern, I would strongly recommmand go seq. simplification. Take the time to study the vacuum hose diagram actually makes alot of sense and taught me alot. I am running 14 psi on stock twins seq. setup and the transition is smoother than ever, and I truly believe if you want to stick w/ stockers, a perfect working seq setup and the best you can get for a street driven car unless you want 400+ hp, then go a different route. My car makes 360ish hp on a working seq setup and I am very happy.
