Z32 MAF and 550cc Problem Help!!!!

[sr20tom]

I just put in my apex'i 550cc injectors and installed the HKS racing suction with the Z32 maf and a daughterboard. The car ran for about a half hour because i wanted to burn all the exccess fuel. Then i went to drive it and as soon as i step on the gas, the wideband goes to super lean and the egt starts shooting with the car bogigng. Then i parked the car and changed the plugs. The same problem happens. The car starts and runs perfect for about 2 seconds and then starts spottering and stalls. After unpluging the MAF the car idled witout the sputtering and ran as though it has no MAF. (Super rich and cant rev past 2.5K). As soon as i plug in the MAF, it runs perfect for 2 seconds and sputters to death. I donno if the MAF is good. What can the problem be?????
I just wanna :2f2f:
