Boost, Tune And Injector Questions

[ashneel]

hey guys just wanted some adv on what to do.

atm my 34 is tuned at 18psi with highflow turbo, FPR, FMIC high flow fuel pump and high flow fuel rails running 242 rwkw.

was playing around the the PFC hand controller and noticed my fuel injector duty at full throttle hits 90%. atm im running stock injectors and have been told its not good for the injectors to be running at that rate. is that true?

so i have decided to get new injectos but while i wait to get em thought id turn the power down a bit. so my next question is i have a manual boost controller which is set to 18psi if i turn that down and run the car at 14psi can it be done? or will i need to get it de-tuned with the PFC???

my thinking is running 14psi will obviously change the afr which will then atleast keep my injector duty down.

so ye can i just do that?

My advice is to get a set of injectors for your needs mate, id say 480cc, 555cc tops

ye injectors will definitely be changed but thats when funds are available for them but for now i just want to know to run it as safe as possiable do i just turn the boost down so its not running as high needing a shit load of fuel up top or do i need to get it tuned for low boost?

If it's been tuned properly and not just for WOT; reducing the boost will work just fine and the injector duty will drop with respect to the reduced airflow.
