Loss of power in 3rd

[Baz-GlanzaV]

Right best way to explain is if was pottering about 2k rpm and put my foot down boost kicked in and started climb (as it should) it hit 3k rpm then behaved like it was spinning the wheels up but the revs held and then started to climb again once got to 4k rpm doesn't do it in any other gears no clutch judder, selecting gears is fine as normal. I even stopped and gave it the full shabang through all gears and it held and boosted fine. To me seems like the clutch slipped but I'm unsure. To help answers in running standard boost bypassed 2.5" turbo back exhaust no other mods. After a bit when I nearly got home it didn't do it at all. Is it the clutch or is their something more drastic happening? Any help is much appreciated guys. Sorry if it's a repost.

If you can get it to do it all tide let me know bud and fetch in down

If revs held and didn't climb it's no clutch slipping or spinning

Revs climbing and road speed staying the same indicates this

I may do tomorrow bud read a thread in engine bits seems possibly like a misfire. But just took car out and it like hesitates at 3k like it's spinning up then climbs up to 4k then increases normally there after.
