When in 2nd gear I have full boost on both Primary and Secondary but during transition it would dip down to around 5 PSI. However, when in 3rd gear I get full boost on both PRi and Sec and also the transition is perfect...just dip briefly down to 9/10 PSI.

So basicly, the boost is fine throughout the powerband with only the low drop to 5PSI while transition to 2ndary turbo on 2nd gear.

Any ideas or anyone experience this before?

Thanks.

 

should only dip to about 8psi on a stock ecu

 

What are your mods? I am experiencing similar problems with my car with DP, CB, Intake, SMIC, and M2 stage 3 reprogrammed ecu.

Basically, there is no way to eliminate this problem with a stock or reprogrammed ecu. I have messed with the waste gate and precontrol pills until I am blue in the face. I am thinking about going to the Power FC.

Good luck,
Jeff

 

Yes, that's stock...I am running slightly higher in boost.

It's only dipping that low on 2nd gear but it's fine in other gears.

 

Hey, I don't have stock ECU, I have PMS with most of the bolt on stuff. Do you have this problem with all gears or just on 2nd like me?

IM me if you're on AIM: surpernsx

Thanks.
