what spark plugs to use when making 24+psi boost

[XSboost]

I current have been running AC CR42ts gaped at .28 with much success car has gone 11.004 @ 127 with 23psi I would like to run more boost but It seems to be blowing out the plugs when I go over 23psi I am not getting
any knock on the scanmaster and the a/f is 11.6 with tech edge wide band O2. smaller gap or some other type of plug?

You could try another coil/module. Do you have a volt blaster on the car? It usually helps the ignition.

Car should be much quicker with that mph......

Going to the track on friday to give it a nother try, the 11.004 run was with a 1.86 60ft. thanks for the input.

I use CR42TS gapped at .30 and run 24# on up to 27# without a problem. I would look at a weak coil or ign mod as mentioned above.
This is when a Caspers tester is invaluable.
