More tuning woes

Since last night when I put in the new plugs the car ran great on the initail run. Now, thankfully I was logging at the time and when I was nearing redling the car felt like it hit a brick wall, I wasn't expecting that and hurt my neck a little bit. Here is the log.

At 6230 it went way lean, this is the modified version from last time and still had to add a little more fuel but the injectors are prety much maxed out. The MAP is very very close to my boost gauge. Also I noticed the MAF MOD hit 2100, I know that there is a way to change that, to raise the maximum allowed MOD, right? There rugular ecu timing threw me a little and didn't know if it was right or not just by looking at 4016-4873. Before I hit the "wall" the car ran great, pulled really hard and no knocking. If you want more info please ask, and I will tell.

You hit fuel cut. No doubt. You need to raise your Max MAF to something higher.

Same thing I was thinking but wasn't too sure. I don't really want to screw with any of the settings until I understand what they do. Some of them are pretty easy though.
