Did you replace the cut MAF yet? That will definitely cause a poor signal if the maf is still your modified MAF. I found that on on my cut maf too. You have to spend many hours with an emanage to come up with a program that will actually work for a MAF, and the emanage is significantly more powerful than an SAFC!
Swap out the maf if you haven't done so. If you have already replaced the maf then put your stock injectors back in for the time being until you get everything dialed in.
When you get to the dyno you can use the A/F data to determine whether you need the 19's or not.
If you do it this way then you will minimize the number of changes and you will be able to squeeze the most power out of your engine.
