Was wondering if anyone here could offer some help with boost issues I am having.

I have been running an apexi power fc for about a week now. My low boost setting is at .75, with base duty at 56%. I can consistently get boost of over .80 and i have hit max of .88 on this setting. I havent even attempted to set the boost on my higher setting at .85 since i can hit this on my low setting. Does this indicate any potential problem? Can i just lower the base duty %? and how much? and would this cause any problems?

Also according to the pfc commander, when i hit .88 boost, max injector duty was only 59% and highest ever i have hit was 75%.

thanks,

rob

 

YEAH, What he said! I am having the same problem too

 

do you have your primary and secondary turbos BOTH at .75 and .56 for duty? what boost do you want to run?

and have you compared your boost gauge to the powerFC? I find my power FC is not accurate much past 11 psi.

 

I have my primary and secondary set at the base map default...at 3rd gear WOT I see 11- 8.5,9- 12.5 PSI on the Defi linksys boost gauge...on the PFC I can't remember what it was but it was about 1.5 PSI lower than the defi gauge...

I guess my real question is, if I have Intake, CB, DP, with Basemap on PFC what are UNsafe boost levels?

 

I ran 12 to 12.3 at the track consistently with no issues before I got my fuel upgrade. With the power FC I see no problems with 12 lbs. don't go over that for long if you don't have a fuel upgrade.
