I'm really curious cuz the video are showing close to 8psi of boost at about 6k-6.5k

I was thinking that maybe you have a smaller pulley. I like it that way better rather than always redlining just to reach 8psi of boost

No it is the same pulley as before, The car was making 8 psi on the dyno and it made little a little more on the road. also the boost did not change wither we had test pipes or factory cats. although i did tighten the bypass valve as much as possible to give the car a better boost response and maybe that 's what did it .

And yes you are correct the beauty about this set up is that you don't have to red line the car to get all the performance out of it.
