You probably need something in the 44 lb/hr and then remapping.

remaping i was thinking that those mrc chip sets was preset for a certain boost and the motronic still adjust timing /fuel/ ect ,when you run biger injector?

44 lbs gasoline per hour. Racetronix are 37 lbs/hr.

Racetronix have all sorts of injectors. The ones "we" have used are the 37 lb/hr

i did run them last summer it was ok but it was lean little bit! my english it not so good so you did misunderstand me! i have mrc chip set stage 3 and i want to no if the motronic stil modified the timming/fuel/boost if i go litle biger on injector

With some injectors there's the possibility of significant variation from one to the next which could have a big effect on tuning - since we typically don't have a WB 02 sensor for each port.

I wouldn't buy anything that didn't have fuel-flow documentation for each injector. I found RC (Russ Collins) Engr had the tightest numbers, and they flow every one. Spendy though.
