Max boost levels post dpf delete & stage 2 tune

HeyDouglas · 06-20-2016, 10:35 AM

I was keeping an eye on the boost levels the other day and noticed it peaked around 52 psi and settled at low 40s. The car has dpf delete and stage 2 tune. It pulls nice. No codes or weird noises but that seems pretty high to me. I am using torque pro to check on it. What's your take on this?

Are you using DWR's custom pids? If not, then that # could be skewed, or it could be reading EMP which would be in that realm I think.

Just realized, I might have been using a different account (mazdaspeed 3) that I created for a friend so he can check his car. I will double check tonight. That might explain the high readings.

With Jareks tune I max at around 34 usually

Thanks mrdeezy. I will check again tonight. At least I now know what range to look for.

I agree with above and suspect you're seeing Exhaust Manifold Pressure.

On my car, the relationship between IMP and EMP is usually ~1 to 1.5.

You need to make sure you're subtracting the ambient pressure at sea level (14.7psi) from your readings.

I doubt Torque Pro is doing this.

False alarm guys. As I suspected, I was logged into my friends profile last time. Everything checked out ok today.

Black smoke is some unburnt fuel, jus because you see it doesn't mean always bad.
lots of things you dont see are more harmful 2 you

I have Jarek 2.5 I get a cloud of black smoke at my first wot. After that the wot smoke cloud is smaller. Driving normally no smoke at all. It does stink though at all times. These readings are not from torque. I have a hard line to my egr bypass to an electronic boost controller. Like I said 34-36 boost spike (actual boost) . I think the guy with hybrid turbos nc335d was getting up to 40 psi.
