Bad Rev Hang

20-07-2014, 19:36
Hi everyone,

My EVO IX FQ300 has really bad rev hang, had it remapped, clutch changed serviced regurlarly however not sure what the problem is and how to fix it.

Someone has told me that this could be due to the hks dump valve that is on the car or could be not enough cold air going into the induction.

Can anyone help?

Just to add this only happens when the car is warm and when coming off boost, it sticks to 2k revs have to dip clutch in and out in low gear to lower the revs which can get annoying at times.
