needs a tune and a TPS adjustment.
eyes burning is usually due to overly rich conditions in combination with retarded ignition timing, ie you finally got the car to go into 5/20* idle timing and now the overly rich condition is more apparent. the hesitation at 2k RPMs likely is a mapping issue.
if you have a datalogit save the map and initialize the PFC, it should run fine with the stock base map out of boost until you can get it tuned.

missed that it was running a single with upgraded IC, yes you will likely need to take some fuel out in the lower range depending on the turbo and efficiency of the rest of the IC system. with the single T66 it won't be nearly as responsive below 3k like it was on the twins so be prepared for that.

The map you posted is the correction map. What you need to do is verify the basemap tab has data that is realistic. The correction map can be all 1s as long as the basemap is configured correctly. Connect the datalogit to the powerfc and do a read all and then click file->compare with the stock maps included with the FC-Edit software under the basemap tab.

I wanted to say thanks for all the advice and support I recieve from this site and the people on here as well. In this case my problem was all in the tune and I wasted countless hours of research and tinkering but in the long run I should have just tuned the car to start with..... Lol it runs like a rapped date now though. Look on pump gas and 13 psi of boost....:::: ear to ear smile all the way home until I seen the puddle of oil under the car right below the turbo ( drain line from turbo I think) :-(
