I'd check for a leak in the hoses between turbo and intercooler and intercooler and inlet manifold.

As above, but also check the Turbo actuator that it isn’t sticky, that will cause it.
If it gets hot and sticks it’ll limp mode, a little 3 in 1 oil on the pivots will help, but do check what Blackwolf mentions as well. _\Hennessey|Venom| F5/___

Mine got sorted with a new turbo actuator, but it could be a few probs as said above. Making my Defender great again. (Or trying to at least xD)
