I'm going through my "new to me" 07' 355i and doing all of the maintenance, and a few mods. I've changed the oil, replaced the vacuum lines and boost solenoids, adjusted the wastegate rods to get rid of any rattle, replaced the spark plugs (NGK 1 step colder gapped at .020"), replaced the coils (Delphi), adding a BMS DCI and Chargepipe with Tial BOV, and doing a set of ARM Motorsports DP's.

With these mods on a daily driver that doesn't see any track time, and only has access to 91 octane fuel.....what MHD tune should I be running? I'm sure I will do a 7" FMIC at one point, but I don't have it at this time......

Any advice would be great!

MHD stage 2 / 91 oct

My list

1. New plugs
2. New coils
3. Oil Change plus oil flush
4. Walnut Blast plus install a catch can
5. New vacuum lines
6. Adjust wastegate
7. FBO - aka Downpipes & FMIC, upgraded airbox or DCI, inlets, outlets etc
8. Trans fluid is relatively new
9. Differential fluid is relatively new
10. Coolant is relatively new
11. Make sure all oil leaks are fixed - RMS, VC, FCS, Megatronic Sleeve, OPG, & OFHG
12. Injector cleaning like Techtron 20 gallon formula or Redline
13. Index 12 injectors installed recently.

I would have got Eldor coils IMO.
