First auto-x since the rebuild today , did ok car was fun , I missed that low end torque But still always fun driving the FD
<-- my best run wasnt the cleanest
<-- would of been a better run 1.5 seconds quicker bUt i ate a cone . was not opening up enouhg for that turn .

Gonna try some things during my lunch hah ,
I gave it some ***** today on the way to work . with 15C intake air temps . it spooled to around 8 then past 2700 started to boost to 11 psi , and then asoon as it hit the transition it hit 14 psi
so something is off .
I hadnt boosted over 5 psi since I was breaking in the engine , apart from 2 days of some tunning after the engine break in that I started boosting a bit more .
AFR's are in the 11.1's to 10.7's in boost above 5 psi , Under 5 psi I have it at 12 afrs .
so still has a long way to go . LOL But hopefully fixing this little issue will help the low end torque . honestly the car reminds me of an RX8 as it is now .
Little update , I swapped the plugs for the wg/pc solenoids to chec kif thats the issue , instead primary boosted to 14 psi , and secondary 10 psi . so seems like one of my solenoids may be bad . gonna test them when I get home
spool is still slower then it used to be though .

Alright so a little update , swapped the solenoids and nothing changed ,
decided to try something
disconnected the pre control actuator vacume hose and drove around .. in second gear full throttle pull from 2k rpms I built 12 psi max . then 10 when transition and instantly to 14 after transition .
so I dont think its the actual boost control system thats causing the issues .
it didn't hit the 10+ psi until after 2800 rpms and never reached the target of 14 psi .
PFC says max it ever hit was .84 on a diff pull
I used to have to turn the duty cycle way down to control primary boost ..
so something is definitely not right .
I think either the pre control is stuck open . Or the turbo control actuator is open fulltime so its trying to spool both turbos from the get go .
first issues I've had with them . replacing a couple solenoids is a lot cheaper then going to a whole new single turbo system . plus the turbos were just upgraded .
