Definitely worth checking over your electricals before going any further, it starts to get expensive at this point.
Tbh it was always more than likely that the hp pump was going to be below par, the crap fuel will have damaged seals, not provided proper lubrication, etc. I'd suggest replacing the HP pump, as it's so rarely injectors causing this sort of issue. Perhaps leak-off test the injectors first, just to have an idea of how good/bad they are.
I seem to remember you're planning on tuning so the chances are you would have had to do this anyway, i've been there and it's painful but the end result is well worth it imo. If you end up having to go there you may as well upgrade with an R70 too tbh, the cost of a refurb r70 unit is very similar to the cost of a stock refurb.
