He nailed it. You likely arent going to be spoon fed here. A few key words in the search bar will net far more threads than the replies you will get.
Now, just throwing in some larger injectors will probably get you further from your goals as youll need some way to accommodate for the extra fuel, ie tactrix cable and evo scan/ecuflash (if those are still a thing) or making the switch to dsmlink.
Also for reference probably 10 years ago i made 297fwhp with a set of bc272s and a wally 255 on a 20g at 10lb. No tuning, because i was young and dumb, the injector duty cycle was 94%.
Now, if your car is completely stock, the t25 will probably beg you to kill it if you try to push it to those limits.

I'm making easily 300+ whp on a 16g, I was pushing 120% duty cycle on some used 680cc delphi injectors. I'm using FIC 1220cc and I only get 40-50% WOT duty cycle.
