ok so i just bought an 03 evo with a ams turbo 3076/50r on it, it has a greddy profec boost controller and when its on the lo setting there is no problems at all pushing round 15lbs, when its in hi mode its pushing round 27lbs and feels as if i am feathering the gas when its full throttle, the boost guage also drops and peaks all by itself? any ideas on what this may be or why it does this? the guy said it was tuned this way but idk for wat reason. any help is greatly appreciated!!

 

please post all of your settings

 

i have no idea on how to display it? im new to this whole thing and the guy says the motor is built? its tuned on something? unsure on how it has data cables in the glove box for a laptop and it has cams i kno cuz it lopes, but how can i display these without messing it up?

 

Your ebc should have display settings on it. When pressing the buttons on the ebc it should display different set, gain, set gain, limit, etc.
