Injector sizing
Was just curious how much HP 19lb injectors can handle. My friend has an 85 vette with the stock injectors. Hes running the TPIS 700-135 cam (224/224 @.050 - .49/.49lift) cam, big mouth intake, headers, dynomax exhaust, large tube runners, ported plenum, 52mm throttlebody, adjustable regulator.
He's just wondering if there would be any benefit to upgrading to 22lb injectors. He was going to have his injectors cleaned and balanced but I said before he pays for that Id ask about new, larger ones.
Thanks a bunch guys. If i missed something let me know.

He needs a scanner to check O2 readings at WOT to see if he is running lean. If so upgrade to 22 or 24's. He could back off pressure a bit if the 24's are to big or correct for it with another chip.
