On my previous 335i yes, only my current 335is I went straight to Stage 3 after the 1200 mile break in period. To be exact at 62 miles, before leaving the dealer, I had the Dinan exhaust installed, and at 1300 miles I had the Dinan FMIC installed, and then at 3340 miles Stage 3 tune was flashed.

On my previous 335i when going from S2 to S3 there was a big significant difference. The larger added FMIC and the Dinan CAI made a huge difference w/ a 1 PSI increase between the stages.
