Attached is Dinan infro for the N54 in the E93. This was before Dinan marketed Stage I and Stage II as separate products - this equates (exactly, as well as I know) to the Stage II tune now available.
Full disclosure: I'm not a Dinan dealer and have no financial interest in the company, but I've been driving a Dinan-tuned car since early 2007 (E93; now S35i) and am a great fan of both the software and Dinan's way of doing business.
