370z Nismo SC A2A 928 imp/ 9lb pulley
 

Hi Guys I work in my owne car I been of on the car cine for couple years but I am back, pushing my car to the limit, I got 545whp with 12.9 psi top, car is running great, we are starting the process of E85 tune now so I hope we can get good resolts of my car on a safe tune, any question with my build I am here to help, I find out is better to delete VVL and use a set fuel pressure also use a 10g wire to the fuel pump because you will loose pick power and fuel pressure will drop like crazy.

Welcome :hello:, sounds like you have some kind of setup there.

thank you, also I got Fast intention 5 puck clutch and 3'' exhaust with test pipes and innovate gaugers.

Delete VVEL? Did you just swap to hr heads or how exactly did you do that.

Edit- another question I have is how are you at 12.9 psi with a 9lb pulley.

Also who is doing your tuning?
