I have the Go Fast Bits GForce II boost controller. It's amazing. Closed loop correction, multiple settings, I have my WB02, Meth failsafe gauge and Meth kit wired into it to lower boost to wastegate pressure if there is an issue. It has 6 boost presets but I think you can only do 2 off of a switch and the others you have to use the display to actuate. I really like it, I have owned AEM, Eboost2, HKS EVC, Profec B, and a few others and it's by far my favorite.
Alright i looks like I need to eat some crow. I was exceedigly curious about this so I wrote Turbosmart as to whether the EBII controller was doing any sort of correction and here's what they said:
"When gate pressure isreached (GP), the solenoid will cycle at a user defined duty cycle (SP) and willthen alter depending on the rate of change of pressure (SN). "
