Default Low boost on WOT - 12-25-2020, 08:12 PM

Iíve noticed recently that on WOT my boost has been way lower then it should be.

Mods:
JB4 map 2/5
BMS intakes
AP intercooler
Velossa Scoops
2 step colder plugs at .0022
Straight pipe exhaust


For map 5 93 with boostane and 3 gallons of e85: 17/18 psi of boost
Map 5 93 and only boostane : 17/18 psi
Map 2 93 only 12-14 PSI

Attached is a map 2 log. Iím not really sure why my boost has dipped so much and any advice is appreciated.

Not sure, maybe a small boost leak? You should run map0 to see how stock tuning boost looks.

Terry thank you for everything you do for the community.

I spent today doing the cleaning for the valves with sea foam to clean gdi engines. Immediately after the cleaning and procedure, back to normal boost levels. I am not saying that is the cause, but the boost problem that has been plaguing me for months is no more.

I also cleaned the bms cones are reoiled. But the boost dipping was solution was resolved by the sea foam cleaner before I did the cone cleaning.

What is your opinion on that?
