To Dyno...or not to Dyno...?
All...being a relative newcomer to the E55 world (one year in August) I am enjoying learning from the wealth of knowledge on this forum. I don't have a huge interest is modding my car at this point in time, but I am going to have a set of LTs installed on the car soon.
My question...after reading everything on fuel rails, bigger injectors, etc., is are there any risks to having my car dyno'd pre- and post- header install. The car is mechanically stock other than the Brabus K8 package and K&N filters. Is it worth it or should I just have the LTs installed and enjoy? Thanks.....

I plan to put'er on the dyno, but was wondering if there were any inherent dangers in doing so to a stock motor. I only ask because of some of the fuel starvation coversations I've read...I don't want that or anything else to be a factor...just to see a graph with some numbers on it.
I ordered a set of LTs from MBH...they should be here soon. I'm not overly concerned with the numbers...i am "***"ured they are sufficient everytime I slide behind the wheel.
From what I understand about the K8 package...hp/tq are bumped to 530/590 via ECU, there is an additional water pump/pulley and counter flow cooler, and various other components. It's strong and runs very cool even in our recent sweltering 90+F temps. I've been told by Brabus that the LTs shouldn't afffect their package at all.

Well...put ol' girl on the dyno and this is what she did...410.24 HP/499.61 torq. I know, I know...post the graph. Problem is...I can't get the damn thing to load??? This was my first dyno experience...the tech said she ran real rich and that there was a lot of power hiding under the hood. LTs going on tomorrow then I'll spin her up again and see what she does.
