Look at my dyno sheet. Is this spark bowout?

At the end of the pull it starts to break up. My tuner thinks I should go with colder plugs. I am running 17lbs of boost with a kb. I have ngk tr6 gapped at
.030. What do you guys think I could do?

I had the same problem this weekend. Plugs stated to fale at the end of the run. I have been running the NGK TR6 plugs. My tuner had me get a set of DENSO-IRIDIUM-IT22 plugs. Should have then this weekend. I run a Whipple with 19.5 lbs and a 50 shot of NOS. Check out the links.
