Damo...

alot of people think that its just a matter of bolting parts of an engine together and setting the boost for the power you want..


you now know its not that easy..

the person that is doing your mappin etc is more than capable of sorting a 500 bhp engine so i wold leave it to them.

either the head needs to come off or take the turbo and inlet off and see if the ports can be measured that way?


something needs to be done.

does the mapper have experience with the paticular rolling road?
