The cp-e intake I put on my gen2 was about 7% lean.

IMO having slightly oversize ID and skewing the MAF cal is how most intakes make more power on untuned cars. It increses actual load, leans the AFR, and increases timing. There is some flow increse over a stock air box, but that is not where most of the power gains come from. On a load based tune, with an exact match on the maf cal one intake should not make any more power than another. The ECU will not use the additional flow potential because it stops asking for load once it hits the load target.

Anyone have a Maf Cal for me to start at for a Sure SRI with Inlet hose?

Do you happen to know what's the inner dimeter of the MAF housing for that intake?

Then start from the stock MAF cal and see where you are. The stock MAF housing diameter is even larger than that IIRC (2.58"?).
