View Full Version : Variable velocity stacks question

I noticed a gap between upper and lower trumpets. Is this normal? Will it adjust itself once engine is on? Or should I adjust the position of the upper trumpets using the screw at the bottom? Thanks.

When you switch on the ignition they should cycle down to the lowest position, mine would not cycle and kept throwing an error code, traced the fault to a bad connection on the plug on the control unit on the rear right subframe
