At what rpm should a set boost level...

[Flaps]

My RB20DET has a R34 turbo (t3) and has 2 set boost levels. A - .75 bar (10psi) and B - .95bar (13psi). I got my new Trust FMIC about a month ago and since then performance was great, I could notice a higher top end because rears would begin to break traction at 6000rpm. But lately over the last week i have noticed that my boost seems to come on later.

I was wondering at what rpm should a set boost level be reached??

I looked at my gauge this morning and i was only hitting A - 10psi at 5000rpm

Any ideas???

yep i reckon you have lost the settings on the boost controller and its gone back to default settings, with the duty cycle set to default it takes much longer to reach the set level

i think from memory the default setting is 30, and i had it around 50-60 to get a decent boost reponse

i was getting 10psi at around 3300rpm when i had it :slap:

either that or the solenoid valve has stuck again, but then you would only be getting 7psi (stock for r34 actuator)

also i have started to get a tapping/clicking noise coming from behind the glove box, where turbo and BOV are. It starts at 3200rpm and stays constant as it spools up...

That clicking mite be the ECU, ive heard it before on other 33s

Have u reset the ECU after installing the IC and boost controller?

nah i havent reset it since the new FMIC, will probably do that this weekend.

all apexi solenoids click as the start bleeding the boost, but you should have noticed this before maybe its stuffed
