I have just installed a turbo kit to my 98 gsr, and my clutch and gas pedal pop when I first put the car in gear and start to drive. It does it in every gear. I can't find anything in the engine bay that is loose so I can not pin point a direct area where it could be coming from. My FMU is not currently mounted, it is just sitting in there (but it is secured). I don't know if this could cause the problem. I appreciate any help I can get.
