Default Hitting 100% IDC with stock turbo?

Is it really possible to hit 100% IDC on the stock turbo at 16.5psi max?

I just about freaked when I saw my UTEC log for the first time.

Thats first gear with the shift to second at the end. Hit 100% in second, and almost in 3rd before I ran out of room to run.

Also what does it mean when its just ---.- for the IDC?

Looks like the STi injectors and pump will be going in sooner than I thought now that I have a UTEC I just didn't think there was so little headroom on the stock ones.

Rob,

IDC is about airflow, not about PSI..

Put a 20G on your car... you'll be all out of injector by 12 PSI....

Can't make head or tails of your log.... But, if you are running close to static on the injectors with the stock turbo, you are probably way too rich. I would call Turbo XS and email them your logs, for a bit of help...

As you know by now, yes. You'll hit 100% IDC at even 15.7psi when it's 40F outside...

I used to hit 100% IDCs stock turbo/ injectors by 5200 rpm with my stage 3. Your probably not that rich, so only remove fuel if your using a wideband.

Just load up the stage 4 map, but control your boost levels to stock tapers. The stage 4 maps are fleshed out enough to handle you until you get properly tuned.

If you see knock, then do a #1 log and either give it to me in IRC, or post it here, either way, recommendations can be made.
