I just have boost gauge atm and no do not have tatrix 2.0.

 

Which can help

 

I can lower boost with tatrix?
how does it work exactly?

 

You have to have tatrix 2.0 openport and then download ECUflash and you can change it from ecuflash but you dont have to change the boost settings if you didnt do anything on ur car i think its a failure maybe a damged vacuum hose or not connected properly put a zip tight on them

 

With a tactrix you can do ecu modifications, tuning, logging and other great things.

But I think you need to keep it simple and find out why you are getting misfires. Maybe have a fuel pressure and air/fuel ration gauge as well will help you out.

Fix what's broken and then make improvements.

I'd guess to say its a bad fuel filter, ignition coil, or boost controller related.

 

Fuel filter should be cheap to replace. Pull the fuel pump and look at that sock. Triple check all vacuum lines. Make sure your fuel pressure regulator vacuum line is good.
Disconnect the battery for a few minutes just to reset fuel trims. Get a wideband ASAP.

 

Hey guys sorry took so long for reply. So my vac hose connecting to cold side of turbo was singed through from the fan shroud.
i replaced the hose and all was working fine no more boost cut. However i am now only maxxing 10 psi on wot.. any clue to whats going on??

 

Check where the vacuum hoses connected for rubber debris. If nothing. Treat it as a new problem. Boost controller? Boost leaking? Several reasons as to why you're under boosting. Stray new thread and post alot file. I know that helps the advanced members on here.

 

Okay thanks i heard i need to use oem boost hoses could that be the case

 

Not really, I'm not an expert in turbo dynamics, but I'd figure that if the hoses are wider than OEM the reading would have a delay, but it would be milliseconds and unnoticeable.

Keep us posted?
