Recently I've spoken to afew mappers,, all of which seem to think or at least have the same view, the standard IC setup can cope quite easily with the boost levels thrown at it, even when presented with a strong map
Unless you're planning a DPF delete I would imagine massive HP gains
That said, I'd like to see the difference in power band and delivery.
In my past experiments with cars, I removed the DPF on my GT170D mk5 golf, massive difference, then I added and uprated S3 intercooler (8p shape) - the power was actually less peak, without having the map adjusted to compensate, but the power delivery became more urgent and full boost archived allot sooner and latest allot longer at the top end, not bad for a PD engine
Just my thoughts .... It'll be interesting to see the differences that will or could be archived
Always a pallbearer never a corpse....
