Message What exactly are the signs of a boost spike or feedback? Is there any difference in sensation/read out between these? [I know the former means too little gain and the latter because there's too much.]

On the display, if you are running optimally and looking for 14 psi, will the boost controller read 140 and hold it consistently? Or is it normal for it to flash from 142 to 135, to 147, etc. Or is a boost spike more like going up to 14, then down to 9, then 12, etc.

That is, is that just slight errors in the readings (normal) or is that a noticeable boost spike? Right now the car pulls strong but I don't know if my boost controller needs adjusting... I need to know what to look for.
