Hahn gives you a base map....He will tell you direct on a phone you will need to tune the maps yourself to get to where your going. Hahn will not tell you to just adjust your fuel pressure to compensate for higher boost. Why is that hard to understand? If your not going to listen to us then dont bother asking questions. The portfueler was around 10 years before Hahn put it to use....keep that in mind.
