Does the chip have a SSS or 555 on it, some think they look like SSS others say 555, this would point to a std chip, that may have been re written, best bet is to get it on the rollers where afr can be seen under load etc, safest way of doing things from your point of view, just set to std pressure then get a fuelling load check done, cost 1 hours RR time but could save your engine.
