Alain, you said that putting 24 lbs injectors helped a bit. I did the math, and unless I'm wrong(very possible), 24 lbs injectors only supply 7% more fuel when we just added 20% more displacement. According to my numbers, 27 lbs injectors would give you 20% more fuel over our 235cc stock injectors, but since I don't think or haven't seen 27 lbs injectors for sale, it seems 26 lbs injectors would be most adequite for the 2.4 on our motors, adding 16% more fuel over stock. Is there a reason why you went with the 24's over the 26's? Thanks for the help.
