Juicebox3 in my E89 - dyno chart attached

Went in for a dyno today. Stock map vs map 5 on a JB3 on a otherwise stock car.

Numbers are whp on a mainline dynolog.





AF seems pretty rich after 5k rpm. not sure if a tune can solve that.

Cool mod.

They may not had enough cooling on the front end of the car. Trying to find the Dinan vids on youtube where he was saying you can't hardly get enough air through the radiator to prevent the sensor from kicking and making adjustments to the a/f, timing, etc.

I'll post when I find it.

How about the torque gain?

Any overheating issue?

+48HP or so seems a bit low for a JB3 on map 5? Seems to be a big dip around 6000RPM, where the curve looks as though it should peak.

guys seems like i was on a wrong map during the dyno run . 7 instead of 5. was advised to run on 5 again on the dyno as I do not have any supporting mods. Will do another dyno run soon and report back on the findings
