Ok guys, got my 97 GST that is bone stock except for the injen intake and filter. I just changed plugs using the BPR6ES and new NGK wires. At hard throttle or WOT, i get what feels like a miss. If i let of the throttle just a hair it runs fine with no miss. Think for some reason i am getting fuel cut? I looked at my plugs and they are a brownish-white color, more brown than white though. No i have not gotten a A/F or boost gauge installed yet to check and see what boost or a/f ratio i am at but i am thinking that with it being mostly all stock that there shouldn't be a problem. Also, at around 2K rpm, my tach is jumping from about 2-2200 or so and surging a little with the boost gauge still reading boost unless i put it in neutral and rev it to where it releases pressure. ANy thoughts?

It almost sounds like a plug/wire issue? Did you gap the plugs correctly? or do they come gapped? I've never used the NGK's, so forgive me if i seem ignorant.
