The advantage/need for a hpfp on 93 is not clear. Some tuners say there is a gain while others are say there is no advantage (or they are still testing).
With 95+ or an E mix you can use the HPFP to avoid lean conditions and create a higher HP output.
BUT beside the above I would assume Stage 2 (aka DP) is always needed as the boost needs to be turned up to "make use" of the hpfp which might/should/is not healthy for a car with stock dp.
