Who said this was a twin-turbo. They could be calling it a bi-turbo because its a twin scroll. I would doubt they would do that much R&D to put twins on. Just not logical. Easier to put a bigger twin scroll to get the numbers. We all know what a bigger turbo will do on this platform with the right tuning. I just tuned my buddies n55 FBO xi and its quick. It was at 365 awhp and I walked all over him. Now he can hang in a rolling 3rd gear pull and I'm making 450 whp and 500 wtq. Unfortunately we didn't have room to really see how it would hang in 4th, but it won't be long before PIR is open again and we can go play without traffic. I think it's only a matter of time and we'll see big numbers on the N55's, just need a turbo upgrade option and thing will get interesting.
