Welcome to the forum!
The FAQ has a couple of good threads on what performance mods are available. -

To gain noticable power, back out the max power screw a little.
Also check that the spaceship diaphragm is rotated to max.
If too much smoke, or if coolant temp rises much, then back off until you install a thermocouple in the exhaust manifold to keep an eye on temps...
These are quick adjustments, that will give you a feel of power increase. -

What is this "spaceship diaphram" you speak of?

Sorry,
The Aneroid lump ontop of a turbo diesel pump, that will have the 1/4" air line running from the inlet manifold to it.
Inside the lid is the diaphragm, and it's spindle under this is the ecentric [offset] boost cone, that on the GTD is the steepest and most in demand by non GTD owners. rotating this alters the rate of positive feedback of more fuel for more boost... -

Don't make this change with installing an exhaust gas temperature gauge first and noting the temps under a variety of driving conditions. If you dump too much fuel into it you'll most likely end up damaging the engine. The easiest and safest way to get more power is to move more air thru it with a larger diameter exhaust system and a fresh air intake, then install an intercooler if it doesn't have one already. -

Are you sure it's the easiest way? It's only if you go to extremes, that you endanger engine. For ease of an increase just rotating the aneroid, does not give enough fuel to burn anything out, It just gives you the extra fuel a little quicker. It was just to give you a taster. If you want ooodles of power all the time, then a EGT gauge is important.What is this "spaceship diaphram" you speak of?

There are no $10 EGT gauges over here , as we don't all have a Sopwith Camel in our yards. Having a larger exhaust is a good thing, but needs fabricating. Changing the air filter can make a huge difference too.
We here in the UK don't have much, but we do still have a supply of GTD's and they come with an intercooler as standard

Yea, but only 3 of them, or is that Quantum TD's which are becoming like hen's teeth now... Oh yes and that red GTD that granny gave me
