I just got a set of RC 440cc fuel injectors installed on my car, after instaled them, the car didn't running good. sounds like the car didn't get enough fuel, and the car died once on the road one night when I was on the way home, it starting fine now. but just not running really rich, it blow blue smoke out from the exhaust when I just start it the car, and after couple mins it back to steam. one of my friend said need to get the car tuned to make everything run right... I have bigger injectors now but my computer still thinks I have the factory injectors in.. until I get tuned, I will be running super lean because for example %50 fuel delivery on stock injectors is gonna have more fuel spraying out than the stock 50% delivery on the bigger ones...
thats what he said. anyone else think what the problem is? or just like he said, get the car tune. I have hondata S200 with boost options.

The injector correction factor won't always perfectly correct for using a larger injector. You still have to check and then re-calibrate the fuel base map as needed to get the air:fuel mixture right for the entire map.

 

anyone else?

 

come on I need some more help please
