MAx boost I saw is 13... Duty cycle of turbo's high ? How to read this to determine if I still have a boost leak - No codes, I couldn't do many WOTs

007_e350 · 07-09-2013, 11:47 PM

also idle RPM when oil at 240 jumps to 800 - 825, cold car (after warm up) is 600 .. Is this due to fan ? AC was kept off

Anyone

has to be wot in 3rd 2500-6200 or so in order to give you informed info

^ Like he said you NEED to be wide open throttle the entire time from 2500 RPM To redline in preferbly 3rd gear with traction control completely off. (That's holding the traction control button for 3+ seconds).

You don't need to make another thread just post a new log here.

does not look good ....

007_e350 · 07-13-2013, 09:36 AM

Can someone explain whats wrong with that graph .... I see the boost isn't climbing up till abt 4k RPM & goes upto only 15 psi ... target was asking 14 since 2k RPM ........

I checked DME codes, it had the Overboost code CEL on (butI didnt get any CEL..., JB4 auto-delete is disabled) ... whats going on

the PWM came down to 28 or something is that normal ?

Did u find the leak with a pressure test? I don't think those inlet sections are meant to hold much pressure.
