My next test would be Brisk DOR15LGS!
here the email i got from BriskUSA and i post it here for info. exchange!

With nitrous we recommend heat range Brisk 14The measured gap is about 2.5 mm. However LGS style plug is a semi-surface discharge plug that requires significantly less energy to jump the gap than standard plug. This plug works well in applications where recommended standard gap is .8mm and up. The stock ZR1 use DOR15LGS, if modified or nitrous you should use DOR14LGS or DOR14LGS-T ( a version with reduced gap for high compression, forced induction or nitrous applications).
Best regards,
Chris
