I have been meaning to post this dyno. Anyways here is my E50 dyno with stock turbos and stock inlets. It was 90 degrees on the day that I got on the dyno so there is certainly more power if was 20 degrees cooler. I also had some throttle closure going on as well that I will need to address.
I plan on getting Pure Stage 2 turbos with inlets soon so I might not even mess with my stock turbo tune.
I also had an opportunity to take it to a 1/2 mile event and here are a few videos. I ran between 139 and 140 all day. I beat a FBO C5 Z06, smoked a C6 ( I will upload that video later), got smoked by a 750whp GT500 and lost to a Single Turbo 335i.
