    Please help me with this TBSS, very irratic stft

    I know that the maf wasn't dialed in perfectly yet but i fought this car for 8 hours today and it kept putting me in different directions. At about 5 minutes into driving it on the datalog it maxes out the stft on the positive side. Mods are a 1900 magnacharger, pcmforless 4" maf and ls1 fans, 160 thermostat, long tube headers, injectors are marked 12613412 so i googled them and scaled it to the best of my knowledge. The transmission also surges like it trying to lock and unlock the tq converter at full throttle and i believe i have the misfire tests off I'm not sure what else could cause that.

    Any help or advise would be appreciated.

    Your questions would probably get better attention in the GenIV section since that's what this appears to be.
