Where are we with this yet?
I put my car completely back to stock, and I must say that it drives nice again with the stock dp back on. its like the car reacts better when it knows exactly what the O2 readings are. So my question is... why can't I leave the stock DP in and upgrade with the bigger turbo. What makes this DP so much different than any high horsepower turbo car that still meets emission standards? I know it puts pressure on the turbo, but hey, if your only going to punch it every now and then, so what?
Look at the new M3 with more than one turbo... it needs to meet emission standards so you don't see them going catless as soon as a high output turbo comes into the mix.
