NA swap 1999 NB8, Garett 2560 at 11psi, 3" exhaust, water injection, FM Manifold
 

The list is as follow:
- Adaptronic
- FM Manifold and turbo outlet
- RX8 Injectors
- 2.5" downpipe and 3" all the way with 3" muffler box and no CAT
- Garrett 2560, 11psi
- AEM water injection (ONLY WATER)
- Toyota COP

Running a faily conservative tune, power is at wheels.Looks about right?


BLUE LINE 2.5" exhaust, RED LINE 3" exhaust.

How much boost?

my bad,forgot to mention, its about 11psi.

Its not bad.
Considering your overall mild setup, small turbo, and low boost.
There's room for improvement, esp since you're running w/i, you could probably push it a bit more, but it aint bad imo.

Who makes dyno software that comes up with stupid random X-axis tick values?

e.g. 2810, 4010 RPM, with 4 ticks between them, instead of 3000, 4000 RPM?

Idiotic.

Yes it is very annoying and stupid.

Same boost with 2,5" and 3" exhaust?

Yes, same boost.
Interestingly, boost comes slightly on the 3" exhaust.

30hp from changing the exhaust?

I was running a fairly restrictive down pipe and I changed itnto the fm ones along with the 3" exhaust.

Very possible. I gained something like 40 going from stock exhaust to 3" back in the day. Night and day difference.
