Hi, i have a FD running a single turbo t78 setup,greddy intercooler,hks drager exhaust and apexi PFC..Problem is that my motor was just recently rebuilt and i need to drive carefully for the next 500 miles to insure proper breakin.. my question is that i also have a old school greddy profec boost controller.. Is there any harm to running the car without the profec b turned on if i limit boosting to stock levels.. any harm done. i watch my gauges like a hawk and never go past 5k rpm and keep the boost at 10 psi or under..Ionly ask becuase i think my profec b is broken and i want to order the newer one.. please let me know.

 

Turning it off is probably the 'safest' thing you can do, it'll limit you to your wastegate's spring pressure.

 

yea just turn it off or bypass it all together

 

thanks guys. so at this rate its best to leave it off and go with no to little boost until the 500 miles are up and than get maybe a new one.. right? thanks in advance
