I got a lot more seat time with the headers on. I have a bit of throttle lag off the line to low/mid RPM. I think it could be as simple as resetting the adaptations. If that doesn't solve it, I'll be sending Zak an email asking for the adjustment on the tune as I have the Simon tool and don't need to go to the shop for changes.
Upper RPM say 4k+ the car pulls much harder than ever. At 5-7k it screams. I'm VERY happy with the headers and can't say enough about them.

I did the 3 stage intake manifold off the 330i and AA stage 2 tune at the same time. I cant really comment on one without the other. To sum up my feelings on these two mods..."Night and day". This should be everyone's number one group of mods for any 325i.
