Unfortunately the car was last tuned with a couple small boost leaks. I finally got around to fixing all of them, and now the car is, I believe, hitting a limiter. Boost Target VSS is set to 20 from 16mph on, but the boos gauge is hitting 24-25 - the car will sputter at around 5500rpm @ wot. Fuel cut is set to 27. Boost error duty is set to -10% from 13.80psi on (0 is at 0).
Should I adjust the boost error table lower or just lower Boost Target VSS more? I have a couple logs if anyone cares to take a look.

I noticed something funny in the nitrous ignition table (which controls the meth). There were 0 values for 25 and 28psi. If I hit 25psi timing would've jumped from 2.81 to 0 starting at 5450. Is that intentional?
Also, WG Base Duty Map there was a jump from 67.2 to 39.9 between 20 and 23psi @6050 through 7000 rpm. Everything above 20psi is at 39.9 actually. That can't be right?

i have noticed mine will have a glitch like that once in a while two, after shut down the map will have a couple cells that drop to a -0- value in my fuel table. not sure what it is
a good thing to have handy is an uncorrupted file on your computer to compare your map with.. for some odd reason sometimes when you connect to the car the weirdest shit will get jacked for no apparent reason...have no idea why either..something to do with the way the port communicates and it seems tohappen more when you use a usb to serial
In my case with the nitrous table, the values were actually 0 - I changed them to reflect the values below.
Last night at the track the car kept bogging in first off the line, this was corrected by turning down the 2step (had been turning it up all night and at the max of 5800rpm it was building 12psi on the line). After that the boost in 4th gear seemed a little low (20psi) considering boost went from 22-25 in 3rd gear. Trap speed was low at 109-114 all night. The last run I turned up the timing a bit in the top end and the trap was 116. It was still a slow run at 12.7.
