As a perspective E55 AMG buyer Ive been doing alot of research over the last week and am a bit shocked to find that aside from the Speedriven Standalone ECU, to make changes to a tune (from any of the vendors for any reason) you have to go through an email circle jerk. Now these cars seem to run super consistent numbers both on the dyno and at the track, and I could be way off in thinking this is a shortcoming or a need, so I hope a few people will give me some perspective. Its just been 10-15 years and 3-4 vehicles since Ive had to email tunes back and forth to make any change, reminds me of sending off prom's back in the good old days. And makes me feel a bit like I'm 11.


Thanks

From what I understand, the tune files are altered stock files which are VIN specific for the car in question. They are also based on dyno tuning with various mods so they are loosely tailored to your individual circumstances with a margin of safety for between car differences. However some tuners have handheld devices you can store several tunes on so once you have them you can change them as often as you like without any circle jerking. For most people it is a 1-2 time event and you are done. For me I got a pulley and tune. I will get a "re-tune" when I get longtubes and that will probably be it forever unless I go for a 80mm pulley sometime. If you are really into trying dozens of different combinations of pulleys, headers, throttle bodies etc then yes you are in for a lot of emails.

I have a Eurocharged tune on my E63. I had them do a re-tune, at not cost to me, and it was effortless. It took hours from when I emailed them to when I had the new tune on my handheld and ready to go.

The Flash tunes on these vehicles are excellent. So good that we have been at the dyno before with tuners only able to squeeze 4-5 hp out of the flash file. You do always have the option of doing remote dyno tuning aswell. For the price of the tunes on the 55k cars, and the fact that we offer free re-flashes for life, It doesnt get much better than that. We also have a 24hr turnaround on flash files. and as TW2 mentioned, these files are built specifically for your modifications.
