Year/Make/Model: 2013 Mazda Mazdaspeed 3
Mileage: 193xxx
Location: Ontario, Canada
Concern: Low Boost Condition (Target = 20psi / Actual = 11psi)
DTC's: None
Modifications: Autotech HPFP internals, JBR 3.5in aluminum intake system, Corksport racepipe, VTCS delete, Turbosmart Kompact 50/50 BOV
ECU/Tuning Software: Cobb Accessport V3
Tuner: Freektune
Is the concern intermittent? No
Can you duplicate the concern? Yes
Recent Repairs: Recent oil change + trans fluid change
SUMMARY:
I have been having this issue for a little while. It started while I was out driving, and I noticed on my access port that I was only reaching 11psi at wide open throttle (3rd gear). The car is on a freektune pro tune running 93 octane fuel, and was previously reaching 20psi for several months before this suddenly occurred almost out of nowhere.
I've posted two logs:
- "Normal" was recorded a couple months back when the car was running healthy
- "Underboost" was recorded yesterday and shows that boost pressure maxes out at around 11psi. Another strange thing I noticed in this log is that my AFR remains stagnant from idle speeds to WOT at 14.85:1. Additionally, STFT remains at 0 with no fluctuation at all.
I'm not sure exactly what this indicates.
Thoughts?
