I think any intercooler is on MQB platform is a nice upgrade.
re Jeff’s tests, the DO88 flows very well, (as you’d expect for a Tube and Fin style) however if you look at the IAT’s after then 4th gear pulls you see it sits well behind some of the others.
As I said bottom line is that any intercooler is a nice upgrade.
Personally I went Revo due to the zero cutting and definitely holds power longer than with no intercooler.
I say just go for it !!!!
