Could it be that our stock heat range spark plugs are getting too hot and actually causing pre-ignition, forcing the DME to pull timing? This is actually a likely scenario for using stock heat range plugs with a S/C setup, from what I've read.
Nonetheless, ESS recommends nothing but stock plugs.

ask ess to explain why the stock plugs work so well ;-) they'll give you the answer you seek :-)
the stock plugs are a high end item and work perfectly in this application, i genuinely see no reason to change them out, as said ess have no reason to not supply a new plug and charge for it if i was needed.
heat soak is heat soak, FI cars suffer from it, the new 1m really suffers from it.... a warm charge will simply cause less power, thats why on cooler days you can really feel the power difference.
id love to know the difference in AIT from a complete stock car at the intake mani and our intercooled cars at the mani.....
here in cold ass england i dont see heatsoak often, perfect FI climate.
