Will a leaking exhaust flex cause any running issues

The engine doesn't cut out just a violent jolt on boost.

I have had a intermittent boost problem. It turned out the mfwt multiple function water temperature sensor needed replacing and the plug had see better days. Could not get a new wiring plug but I did discover the v6 coupe has the same plug and coz the plug is on the top the rubber cover doesn't fill up with crap . So the plug was in good shape. The plug can be taken apart cleaned and reused. You can unplug your mfwt then drive it. Fingers crossed its that. I seen that a lot of people have had trouble with this part before. Anyway hopefully you get to the bottom of your problem. Kindest regards Lynn.

Thanks Lynn I tried the car with mets unplugged , but it was still the same .
My problem seems to be to much boost , not to little

Will a leaking exhaust flex cause any running issues

When Mihnea was live mapping my 3B the first time it would sometimes cut and throw a plume of smoke out the back, he diagnosed timing out so I checked it and had to move the dizzy a few degrees to line up the marks when flywheel was on the zero mark. It was fine after that.

I guess you've checked the WG diaphragm with a vac gauge?

That's one thing I haven't checked.
Would it cause these issues
