I dynoed my 2005 E55 a couple of months ago and made 362whp and about 416wtq. Well, I went back to the same shop today after installing:
bosch 010 pump
Kleemann headers
RaceIQ stage 1 mail tune
ghetto fabulous crush bend exhaust set up
She made 431whp and 438wtq! The power and torque curves look a lot better now too! It's about 55 degrees here now so it's a good bit cooler than my first time on the dyno. Also, power went down on every pull after that but I can attribute that to heatsoak as I'm on the stock heat exchanger. Needless to say I'm happy with the results. I think my big power loss my first time on the dyno was coming from a bad IC pump and the outside temp that day (80ish degrees). Next mods are heat exchanger and smaller supercharger pulley!
