Default reflashed 4.2v to 5.0v now losing boost and other problems

i just reflashed my utec to version5.0 i did everything that it says to do when reflashing. I now an loosing boost as soon as it hits 45k. I just downloaded the base map thay they had on their site and did the new parameters. The car does not feel like it has as much pull to it. I have now noticed that i have a backfire while driving around with low rpms and i also have a hesititaion going into the higher rpms. I amgoing to call turboxs tomorrow and see if they can help, but any help on here would be great. I was thinking of getting on wrxhackers and checking if they had another base map with an up-pipe. If anyone knows what is causing the backfiring please let me know.
