So I'm not sure when everybody else hits FC but I hit at 5500 in 2nd gear and 4500 in 3rd and it runs kinda choppy high RPMs. anybody got any Ideas? I already looked in TSRM and couldn't TS it.

What are you boosting at 5500 in 2nd? 4500 in 3rd? I hit fc before that, I'm at full boost (12-13psi) around 3200-4300 (in 2nd and 3rd) depending on how I accelerate. I have checked for boost leaks. I have all new cooleeze pipes, and haven't found a boost leak, It's a safety feature that I'm going to raise soon when I get my release fork problems fixed. If your boosting at or near stock levels you shouldn't be hitting fuel cut at all.

I was having fuel cut problems also. So i redid my intercooler piping to make sure i got rid of any leaks. But that didn't work, so i installed an HKS FCD. Went out for a ride and discovered my boost leak.... turboxs rfl BOV was to loose. At about 11psi it would start leaking. So i put in a couple of washers to adjust it, and now i'm running .9bar with no problems.
