JB4 RPM Jumping...Clutch Slip?
Ever since I installed my JB4, the RPMs will jump for a second between half and full throttle before accelerating. I don't think it's related to wheel spin since I don't hear anything out of the ordinary.
Could this be a sign of my clutch slipping? I notice it happening in 3rd gear on. Only mods are BMS DCI and I'm running map 1. Thanks!

Car has 39k miles. You might be right about me not being used to the turbos spooling since this is my first turbo car. Would going with catless DPs help the turbos spool faster?

If your RPMs raise then it means the turbos have already done their job at this point.
Either clutch or tires slip, but in 3rd gear that sounds a little hard to make the tires slip. |

Downpipes definitely help them spool faster. Sometimes I feel like my clutch is slipping by the way it drives, but it's not yet. I drive it pretty hard too and mine holds good at 48k. You should have a lot more miles on that clutch with just intake and tune.
