So im thinking about starting the build process tot his car. Just a few questions. Whats the best tune/tuner out right now. Im hearing mixed things on BMS. Dinan I havent heard to much bad things about and I do like the warranty behind it but are there any others Ive over looked?

It seems you have a 2016 550i, which has the N63TU, you can get a flash tune, could void warranty tho. Best bang for your buck and reliable is BMS Tune.

If you have the money for Dinan and dont wanna have to worry about taking the tune on and off everytime you go to the dealer then sure go with them.

Im pretty interested in the BMS its a lot better on price has anyone had any issues with them at all? Whats the most aggressive but safe tune I can go with?

BMS is pretty good I havent really had any issues with it (Stage 1), you can change the settings on it, Im not sure what settings apply to the TU engine tho

I have a 2015 and have been running the BMS tune since 500 miles and catless downpipes since 5k miles with no issues at all.

Before I had downpipes i was running the tune on the 2pm setting, after the downpipes I maxxed out the BMS at the 5pm setting.

Hey bro if you get the Bms stage 1 or 2 let me know, I'm in Vegas and would like to check out your car with the bms on it. Also I'm modded exterior wise if you want to check out my car, it's nice to see a local wanting to mod the 550. Let me know.
