One thing I may throw out, my own car favors hotter plugs. Maybe due to the high amount of meth shot in. Or different chamber design. 
I ran tr5's last night for an experiment.. no issues at 24 PSI. Car ran 6.7@104.8 wed night at 22 PSI. V6 Buick engine.

i am still running a fair amount of meth too even with the race gas.
hey Julio. i need more fuel up top. i have the 3bar map and am around 2.5bar boost. my initial is at 12oclock and turn on is around 10. my gain is all the way up. i have twin 15mm nozels. if i turn up the initial i get a lot more meth but it comes on so fast it is hard to tune around. is there a way i can get more meth at the higher boost levels without it hiting so hard down low?

Hook up a pressure guage to the nozzles and watch it sweep up. If you hit over 150 PSI on the twins, you need to add more nozzle. In other words your running the system to its limit. I would not crank the Initial up on a setup like yours. That creates other issues. Call me and i'll square away your setup. If anything lets add a third nozzle.
So we can make the system progressive showing you a constant increase in delivery. The higher the boost.. the more meth we'll flow in.. but only if your injector DC is low and your seeing KR
