I think that certainly was the case, but we seem to be at a time where manufacturers are making more efficient cats and DP's.
There have been a few examples where people have put DP's on these (S58's) and not gone faster, however there seems to be more to gain on 93 and 98 vs ethanol blends.
The APR tunes on Audi's and VWs mirror this too, DP's on regular fuels make a bigger difference.
May be to do with ethanol running cooler, either way I'd love to see some logs and comparisons.
As it stands the worlds fastest X3M (running a 10.2) still uses stock DP's with cats. |
Interesting. Always felt like spool got better with Catless. Maybe you are correct where the new ones are better. My newest car is a 15. I always do the DP. Old habit I guess. are these custom tunes they are running?
