16 ->12 ohm injectors greddy turbo

[xzerozx]

I have greddy turbo 10lbs
greddy fmic, bov, exhaust, etc with rc saturated 16ohm 550cc injectors
I am experience bad gas mileage (maybe 2mpg worse, hard to tell)
How would i go about changing the 12ohm greddy ep3 cal to 16ohm

would bad gas mileage be due to the injectors not closing fully at part throttle due to its being sent 12 ohm to close and not the sufficent 16ohm?

i can send my tuned cal if needed adn u can chnage accordingly, or u can just tell me and ill do as u say


thank you

There is no easy way to do this. THe best thing to do would be to have a professional dyno operator tune the car and help you with some street tuning...When you say you are getting worse gas mileage....worse than what...stock?

i have gotten it tuned by church (i think u guys work with them) however i dont think i told him they were 16ohm (and i dont know if shawn knows that kpro needs 12ohm ..and ofcourse i get worser gas mileage then stock, but now that i have the 550's ive noticed a worser gas mileage then 440's however ii think i wa sgetting bad gas mileage with 440s due to high s trim at idle... is there ne other things i can do to tell if the 16ohm r hurting me? would they cause boost cuts?

As long as it was tuned with the injectors that are in the car now then it won't matter if they are 12 or 16 ohm...it has nothing to do with gas mileage. Tuning is what matters.
