have we found a way to program out the extra fuel that is being dumped to cause this? I don't know why we have to have this burble pop on decel with sport + on....none of my other porsches do this...why, porsche why.

I would like a lot more pop and burble. Flames even.

Hah. You want race headers plus the gt3 center exhaust conversion. Gunshots and flames.

only one sure way to remove burble and pops...

1) sell GT4
2) buy Camry

problem solved, you're welcome.

It reduces burbles and pops to run in either normal or sport plus modes. Sport is the most over-fueled.

Run 85 octane.

I agree. All those fake noises are sort of cheesy.

The GT4's overrun burbles are solely dependent on the architecture of the mufflers, there is nothing artificial happening such as a fuel dump, the Spyder may be different.
With conventional straight through race mufflers they aren't there, but with the PSE they are, and vary with temperature.

LexVan

Ahhhhh, no. It's exactly the DME overfueling. Simple as that.

Love the pops.... favorite part of my 930 (plus the 3-foot flames)

I also love the pops...on the GT4. I had a Boxster GTS loaner and I despised how artificial the overrun pops were. They sounded exactly the same each time with the same pattern and cadence. In fact, most all cars these days that have the programmed overrun sound this way.

Luckily the GT4's sounds natural and because of that I love the pops.

My story exactly, except the GT4 was preceded by a Carrera GTS, not a Boxster GTS. I was always a little embarrassed by the blat-burble sounds on decel on the GTS, but find the GT4's execution, whatever its cause, to be perfect. Literally the first car I've ever owned in my 40 years of owning cars (including many Porsches) that I didn't want to replace the exhaust.
