The shop that installed it told me it was 30% larger... I never actually looked at it to be honest. I scaled it up a few % from stock with a 3,000RPM redline and accelerated for 100 feet, then scaled from that point and ended up oddly near stock... I question if it was in fact smaller than stock. When the owner gets back in town I can take the calipers to it and find out!
I added some enrichment to 5.0v as it didn't seem to differ much from 4.727 but the 5.0v landed at 279.47 vs 279.227(stock ROM OEM MAF calibration).
Though I tried to keep pulls under 4.9v when possible. I actually setup a custom rom that I continually adjusted to whatever 4.8-4.9v g/s was and flickered the CEL to warn me that I was nearing maf capacity during tuning. I wanted to see how far the MAF was actually going to be usable. And the owner needed a short notice, short time frame tune so I didn't have time to setup a clean SD map. Although I am happy it happened that way because I was really quite curious how much that MAF could support.
