ok i have a built b16 stroker motor with 13.1 comp. i have a eagle fuel rail 350 fuel pump skunk 2 ecu with stock b16 240 cc injectors. car runs good but when vtec hits it sputters/flat spot like it dont have enough fuel. so i bought so h22 345cc injectors now when i put those injectors in the sputter is gone but it runs super super rich, if i leave the stock 240cc injectors in can i just up the fuel presser. i know i need to get it tuned but i dont have the money right now for that i just what to be able to drive it with out hurting the motor .

 

Use the larger injectors. Get a fuel pressure regulator and adjust the fuel pressure.

 

ok ill put the 345cc back in i have a blox adjustable regulator i have it at 40 psi no and its about 45 psi at wide open what should it be about .

 

You may want to get it tuned and vtec may need to be moved to improve or eliminate the bog.... Your injectors are fine for an N/A setup. The dyno will tell you.

 

You have to tune it for the appropriate air/fuel ratio.
