Is it normal that sometime even with the overboost on, the meter still showing 1.0 bar instead of 1.2 bar? touched 1.2 bar for less than a sec then only can hold 1.0 bar through accelaration.
Also there is a metalic like sound (spooling/ exhaust/ turbo leaking???) coming from the right rear when the overboost is on.
Do both Turbos boost come on together or one by one?
How do you know if the turbo/ manifold exhausts are leaking?
Please help.

 

Are you talking about when your car is modified or when it is stock? If your car is modified, what package do you have?? With that info we can then determine if your car performing properly...

 

I have installed the followings: Gruppe M air ram, cargraphics headers, cats and mufflers.

 

raise the rear of the car and look for black soot at the exhaust connections (flanges) of the headers/turbo, turbo/exhaust. That would indicate a leak

 

Welcome to the crappy stock program. Send the ECU in and I can fix that issue Seriously though these are the issues with the stock program. It will also dip down about 5500 and then shoot up right before redline. The stock program has some issues.

 

So you are saying my car is normal? The problem is the stock ECU?

 

More or less yes. You will see blips of 1.2 but when it is warmer out 1.0 is more consistant. Overboost as we have seen does not work as it was advertised to the rest of the world. I hardly ever saw 1.2 until the program was changed or it was zero degrees out.

 

How do you guys get a BAR reading, mine only shows psi?

 

Just switch it in the computer settings to read bar rather than PSI. When you go to set it you have a choice.

 

What PSI readings do you get with the stage 3/4 package in sport mode??

 

I leave mine on the graph and it pegs it until 5K.

 

You Addict!!!

 

LOL, I took it off tonight. 18PSI...stupid stopping gauge. It is not the size, it is the boost
