I have narrowed my search down to Singh Autosport and RPI for a tune / reflash for my 2008 550i. Does anyone have any experience with either of these tunes specifically related to the 550i if so please let me know the results and if you're happy with your selection. My current perofrmance mods include only RPI scoop and BMC filter.
I have not been able to locate a dyno sheet on either tune so if anyone has a personal dyno sheet or a link that would be great.
Thanks for the help!

Got Singh 
I could definitely feel the power gains all across and most noticeable between 60mph-100mph. Sorry no dyno. Hope to get it soon 
Call Eurorev. They'll take care of you.

Thanks for the link, I read through a couple of days ago and while I'm not impressed by the comments I want what is going to perform best for my car.
I'm located in St. Louis so no matter what I pick I will have to ship the ECU out for the tune.

Well, I've been thinking about getting a tune for awhile now. Most tunes seem to give our 550's roughly 20 HP and maybe 24 torque. I'm just wondering if we would actually feel that??? I know the turbo's really benefit from tuning.

+1 I too want to get an ecu tune, and was holding back on the Sprint booster v2...does anyone have both? or would a reflash with rpi scoops, filter and exhaust do the same trick only with better performance?
also do you have to send your ecu in to a certain company to get the flash done?
Thanks for any help

i just got the RPi/ESS Stage 1 Tune, RPi/ESS SMG Tune, and am going in to get the RPi/ESS Stage 2 Tune tomorrow. I used to have powerchip but the Rpi/Ess tune is much more reliable and stronger
