I checked all the vacuum lines on the pass side of the car and check everything nunver neith to, the turbis arent blow and a hose job has been done! He get about 8 lbs of boost and then i dies off to nothing its hard to tell if the second turbo is pre spooling or what is going on. but since i check all those lines i dont know wht to look for any ideas? the car has about 40k on it thank

I'd put the car up on a lift and inspect the turbos thoroughly. Make sure the small horseshoe clip that holds the wastegate actuator arm onto the flapper door hasn't come loose. That's what happened on my dad's R1 in a similar instance.

The non-seq debate is loooong, so I won't do it here, But i will say this.
I went non-seq on a stock ECU, and apparently the stock ECU is tuned for the "dip" in boost at 4500 rpm, and if you have 10psi there, and not 8, like I did, you run lean for a split second. And if you floor it onto a highway on a cold night, KABOOOM, blown apex seal.
So be careful if you're not tuned for it. Thats not to say that many people haven't successfully run non-seq with a stock ECU, because many have. But it could happen, and it is a big kick in the wallet when it does.
