Looking for around 320 - 330rwhp, and currently have the standard RB25DET AFM. Just wondering whether I am going to need to upgrade to the Z32 afm. Don't want to waste $300+ if i don't need to.
So the Z32 afm is a 'higher resolution' meter. Does this just mean that it will be able to read at a higher airflow than the standard afm, or also allows for a more precise tune at all rpm?
Heard that the RB25 afm's are good for ~ 250rwkw / 340rwhp.
Any experiences, opinions, and advice is appreciated.
