Over the last few months, I have noticed issues with my boost. I will be accelerating on a Green light down a straight from full stop and the boost meter bar will barely move, maybe a small notch 3-4psi but the rpm will go up to 5000-6000 range with minimal boost. The car will accelerate but its all motor and little or low turbo. This usually happens when I dont have sport mode on. Less so with sport mode and rarely with sport plus since I have to shift with buttons manually.

The strange thing is that I cannot replicate it every time so I dont think its a leak. At the next light, I floor it and the turbo spools up fully and my boost psi jumps like usual and I get full turbo thrust.

I am guessing that this is caused by the pdk not catching the next gear change thus the rpm goes up and the boost doesnt kick in.

Is this a software issue? a slipping pdk clutch? I have ordered an FVD tune and will be installing it once it arrives in the next week or so but want to get this issue sorted out before I flash. Anyone else with similar experience or solution?

thanks!

 

Sounds like a boost leak to me.
