Car is 2008 Ss with a 2010 drivetrain and peak boost of 26psi s256 tuned on hptuners. The car does the stutter shown in the video but doesn’t always do it, sometimes it’ll run how its supposed to and sometimes it’ll do that stutter and boost cut, i just got the car and yes i was aware of the issue trying to find out what it could be.
Any help or information would be appreciated, and any contact information to a good tuner would also be nice.

 

Welcome I would recommend doing a log and seeing where your trim as your 1st step

 

Know any tuners i can get in contact with to do that or steps to do it myself, car came with the hptuners module and im located in Washington County, Maryland.

 

What mods are done to the car?

 

datalog boost during this.

And it sounds like compressor surge,. That is not a good scenario.

What is controlling boost ?

 

Might be a long shot but when I was having issues with my lower charge pipe MAP my turbo was doing something similar. The wastegate would do some weird stuff and sometimes no boost, sometimes a fluttering.
