YES you are right.
In this moment I still have the stock pump and I'm doing 340HP with 460NM, just made a dyno today after installing the BSH mounts. It run OK until now and still does.
Of course I think this is it's top limit and since I want to go higher I would need a HPFP......and I'm back at the topics' discussion: which one to choose.
I narrow it down to 2: APR and Autotech version 2 rebuild. APR is 3 times more expensive, I've many ppl telling me the AT is very very OK, I'm reading here...still I'm not 100% convinced...
This is really a tough choice for me because I really do not want to through away 600+ USD - the difference between them.
