S5 Tll sudden power drop then gain at 7000rpms
I have a s5 tll with a street port stock turbo and fmic, also has throttle body mod and most emissions and vacuum lines removed, and a N/A tranny. Anyways it runs fine and pulls strong when getting on it but right at 7000rpms it has a complete power drop for a fraction of a second then it goes back to pulling how it was for the rest of the gear. It does this in every gear. Any ideas?

"building" the engine is not a concern, especially If you're only running 8-9k, that's nothing. What you should be concerned about is having enough fuel to support the higher boost levels you will be running w/ a fcd or chipped ecu .
What are the details on your setup? I'm assuming its mostly stock if you aren't hitting fuel cut until 7k. With an intake it was around 6k and with exhaust it would hit fuel cut below 5k....for me at least.

Well I guess it was a mix of a bad fuel pump and a bad fuel filter, i got those changed out and it runs way better top end once its running and I ran it up to 8-8.5k and no hesitation or sputter all was good, just the lack of boost its only hitting about .7bar MAX.
But i got starting problems check this post https://www.rx7club.com/2nd-generation-specific-1986-1992-17/im-stumped-will-not-start-972648/

That's what 10.15psi? It just feels weird cause it has a NA tranny on it right now so it spools sorta slow then hits boost and still runs the gear forever, compared to my friends with a turbo tranny which seems to accelerate better but run through the gears faster and not have as much top end speed.
