Inaccurate Defi Boost gauge

Whats up Evo-M Community;

As an FYI I'm new to the boost game

My car is on stock tune with current mods in signature


Here is my issue in a nut shell - I followed the "No splice/ Drill" technique written up by ZWingerRyRy (Which was Extremely helpful and easy to follow). The gauge works perfectly fine, but is giving me weird readings when under WOT. The gauge sprints to between 20-25lbs then moves back to 15-17lbs. When staying in a gear and rolling into boost it will simply go to 15lbs and stop. I expect this is what is supposed to happen when i go WOT as well.. I cant figure out this problem for the life of me.

Also I thought this would be boost creep, but I read that if it was - The ECU would cut fuel and the car would start to stutter..

Any suggestions...?

On a stock tune that sounds pretty normal. Peaking at 22-23psi and tapering down to 16.
