34 is excessive turbocharging pressure, you must of hit fuel cut, if you have a boost controller you need to turn it down if your hitting fuel cut, it could also be a damaged pipe to the actuator, or a faulty actuator and youll know if you are hitting fuel cut, its like a rev limiter and will give you a code 34.

To clear the code just pull the EFI fuse for 30 seconds then replace it, thats in the fusebox in the engine bay.

i don't have a bleed valve fitted but it did hit the fuel cut off as the car started jumping all over the place and would'nt drive but now the boost guage dosn't go fully up. It also some time's feels like it's misfiring about 2900 rpm on light throttle but not on full

The car starts retarding the timing etc after fuel cut is hit to prevent any damage, so basically itll run like a bag of xxxx after youve done it, reset the ecu and see how it is, and check all your hoses etc.
