There aren't a lot of cheap repairs here. Injectors can be improved with additives but a new set will buy a lot of fuel.

One area thats cheap is the boost signal and of course boost itself. You should measure the boost after the overboost protection switch-over valve. Measure it between the valve and the injection pump. It should max at about 10psi. If you don't get good power you won't get good mileage.
