More timing means more power to a point. Then you start detonating, or start needing to run too rich.

Wow, this mod is a VERY interesting concept. I have a log here that I got this morning, showing my 02's BOTH at .94 running fine until about 5k, where I get knock until redline. Now, I was thinking it was from the stock turbos heating up, now I'm not so sure. My timing at WOT is 25-28, and at 5k it goes to 33, and thats RIGHT where the knock starts. I can post pics if ppl want to see. You can see where the timing ramps up where I have the AFC set to -37, and then starts the knock at .94-.96 02's.

I have a spare MAF, I'm going to try this. I had a VPC before, and know what kind of spool/power difference comes with removing the MAF.

Innovator, I'm going to try this, and post before/after logs. If I can get it to run right. I'll keep you posted!
