you can run map 5 with any mods. map 2 "requires" downpipes.
the 335is engine does not require DP's with if you have quality 93 octane available only the 335i requires it for Map 2. On the custom Map 6 for the IS developed by Terry my peak boost is 16.5psi without DP's using 95/96 octane fuel.

This log is the stock 335IS 93 octane Map6 +1 PSI across the board. Map 2's peak is 14.5, it goes back to the slower timing advance in the 335is. The faster advance curve of the 335i does require downpipes.

The log is after Terry did some tweeking for a slight stumble off the line. The tweek has been incorporated into later firmware versions. My dyno numbers are from the G4 board & an early version of the IS Map6 so I don't know what the G5/ISO is putting down other then its a lot smoother.

If I was running an e85 mix I would move to Map5 because it can adjust to the octane content of the fuel. I can run straight 93 with my setup but am willing to pay a bit extra for the insurance of the higher octane gas.
