i just got a new FD it was rebuilt 462 miles on the motor when i got it now has 2015 miles on the motor.

has a street port stock turbos stock ECU apexi intakes and bov jic catback fmic.

now ive had issue with boost ever since i got the car. primary works flawless 75% of the time. depends on how hot it is here in vegas.

but the secondary ive only had it work 2 times in the past 2 months of everyday driving.

first it tries to boost then once full boost is hit. it automatically forces somewhere else besides the motor and BOV.

could the wastegate be stuck on the secondary turbo? are the turbos going bad?



car only has 98k on it.

i have the non sequential setup should i look into getting that all changed over?

Okay, bit lost here, so lets clarify this and get a bit more info so we can help you.

You are running non-sequential- There is no primary/secondary turbo, they both run at the same time.

What ECU do you have?

What boost are you hitting and at what level do you have issues with?

You only have a cat back or do you have aftermarket down pipe and mid pipe?

I think you might be hitting boost cut but lets get more info.

street port, exhaust, intake, intercoller all on the stock ECU is asking for it..

 

Do you have any way to see how much boost you are running? Chances are, you're hitting fuel cut on your stock ECU.

 

It's not running non sequential I have the setup. It's not installed. I don't feel any boost spikes feels just like my old FD did which was completely stock. But once it tries to engage secondary it trips out. I can hear it spooling but it seems the boost is being rerouted somewhere else.

I am on stock ecu. And unmodified turbos. I bought the car how it's setup. I want to buy a power fc soon but just wanted to clarify this boost issue first before getting the car tuned and wasting money.

 

I only have a catback I have a downpipe not installed.
