If you don't have a scan tool, the alternate procedure is here:

and the TPS adjustment procedure is here:

if it didn't do it before, look at what changes you made and try to determine what would cause the problem. did you buy the TT new or used? i would contact Eric (at TT) and ask him what he thinks might be going on ...... he is very knowledgable and helpful. maybe the chip you're using has a feature called the scanmaster fast update code that is incompatible with your set-up. if you have another chip for the 60# injectors, pop it in and see if there's any difference.
