You're probably way to rich on start up cause you've done nothing with the VE table. So, its probably way too rich til its goes into CL and starts pulling fuel.
Read up on how to tune the VE table, and then turn the maf back on, dial it in and your rich start up problems will probably be gone.
You also have quite a bit of timing in it, esp through the 4000-4800 range, where theres usually a pretty good dip. That dip is there for a reason. I would bet you have a fair amount of knock retard going through that range WOT. Its also too much for a nitrous tune.
Theres a few other things I would do differently for your setup, but everyones different. The timing and the VE tuning are the big issues.
