can *high* fuel pressure cause pinging too?

[schwett]

my pinging woes continue. JRSC'd H22A. MAP mod / BTC included w/kit. 50PSI idle. 70-75PSI "baseline." 100+PSI WOT. A/F always a tiny bit rich under load.
used to never ping. now it does. can't make it go away with the BTC.
could i have induced this by *increasing* the fuel pressure? wouldn't an overly rich or overly lean condition show up on the A/F guage?
thanks in advance.

high fuel pressures causes stress on your fuel system....and usually richer situations...

hell yes you can still detonate even when running overly rich...

JRSC is garbage. I speak from experience.
