Here are some comparisons for you...

In cell 2589:
3.63 PSI of boost. MAFv of 3.16

With your original map, the MAF values at that MAFv was ~59 g/s. After my changes it became ~78g/s. By putting the stock curve back in, I added ~32% fuel! You car was maxing out at 14.84ish before, and wouldnt go any further.

Heres another data point.
In cell 2619:
10.16 psi of boost. MAFv of 3.72

With your original map, you were showing 103.07g/s. After my change... 136.2g/s!
Again... ~32% fuel!
Hey man... sorry, to be honest I didn't exactly understand the correlation before. But now that you explained it in detail... it makes perfect sense, and I definitely owe you a big one and wanted to say thank you again! I have not gone back to my tuner yet. Since it was a e-tune, I went back and checked my order, where I listed all my mods. I put "K&N drop-in filter" as my intake and not as "factory airbox"... wondering if that caused the confusion, even though it shouldn't have. I'll be putting a Samco Afta-Maf hose tomorrow, cleaning the air filter and logging it again... before contacting him.
