Have not really checked for a spike but i know i can hold steady at 28-29 psi. Only messed with it on two or three settings. I slip my clutch on level 4,5 and 6 with the edge so I dont have a real max yet.
Just hooked mine up today.....Im getting 38-40 boost (in the gas)on setting 3. Is that normal or high? The warning was set to go off at 36 which is every time I get into the throttle. I since changed it to 45. Instructions dont give much info. Have fun!!!!
