Hey guys, I just bought a 1997 gsx with a apex'i safc and a avcr installed. When the previous owner had it before me he said it did 380awhp. But yea let me tell you my problem first. So, I cant go past 4500k rpm. Like it gets fuel cut or something. And when I drive it and floor it, it feels like its going no where. But the rpms do clime. Until it reaches 4500k and it feels like it red lining. So the things that I KNOW thats on the car is RC450cc injectors. 16g turbo. open wastegate. garrett bov with a with recirc block off.(surprise I didnt throw a cel) 255lph walbro fuel pump. So I need help tuning it. Tried looking at the manual and its pretty confusing. From going from a 420a to a gsx is pretty crazy. But if anyone can help that would be awesome. I want to set it up where I have at least 12 psi daily.

Thanks in advance
