Had my car back on the dyno......

[datsunboy]

last dyno run was 178HP at 7psi on standard turbo.new dyno run was 221HP at 11psi on GTiR turbo

it has not been tuned yet, we tried a run at 14psi, but it started to detonate.

also the AFR's are very rich.

and the AFR and Power

[CA19DET]

get some fuel management and lets see if you can crack 280whp ay ~16psi, i am sure it feels allot better now and only more to come,

[JDMSIL80]

What other mods do you have in the car?

[Scooby24]

Very nice...yes way too rich on AFR.

Dependent upon timing, knock, egt's etc I would shoot for around 11.2:1 or so....smoothing it out and with that AFR you should be around 240 or so on that same boost

Yea, that AFR, is killing your power. If you can get some fuel and ignition tuning done, you'll be good to go! What other supporting mods do you have?

[datsunboy]

yeah the guy said there was a bit of power hiding in the AFR's.

I'm buying a wideband next week for myself so I can do a bit of road tuning to reduce dyno costs.

What are you using to control the injectors and MAFS?

[datsunboy]

standard ECU re-chipped.
