150 should be no issue... but knowing your A/f's and having the correct amount of timing removed is the best way to go about this.
Get a A/F wide band in your car. The one with the sensor that goes in your exhaust Its worth the $150 for the gauge vs a blown motor. Running rich can destroy your pistons to. Do you have someone that tunes your car?
Get a #7 NGK plug non projected.

Here is more info on my car it is at 24* timing and its on a nitrous tune, but that tune was done to it on stock fuel pump and stock 26 pounds injectours running at 116% duty cycle. Now I have added the walbro 255 and the red top svo 30 pound which is 36 pound to f-bodies and I got an injectour tune so I can run right. After the injectour and fuel pump swap I got an 30 miles more out of a full tank. Don't know if that help. I'm running ngk tr6 gaped at 35.so any help on my dilemma
with all the mods you have and im assuming the A/F has never been checked, i would get that thing to the dyno. whats 300 bucs compared to a new motor, especially since your spraying it. running rich is better than lean but still not ideal, your leaving some power on the table.

do NOT run tr6's anymore.
you want to run a BR7EF non-projected plug. Running a TR6 on a 125 shot or a 150 will eventually be bad news.
Your #6 and #7 plugs look like you have some pretty bad detonation going on.
24 degree's of timing is too much IMO to run a 150...you should be more in the 21-22 area.
Im not no nitrous Guru but I know the basics. Maybe someone else can jump in with some better info.

Gap 32 NGK plugs you can order them thru Nitrous Outlet or a tech sponsoner im sure. I would get a box. Look like your timming is to high and you do have detonation going on. I would not go up in shot until you get the A/F lined out first.
