Message	My injectors hit 98% duty cycle at 13.8 psi. Circled at the lower right is the inj.duty gauge, peak hold is the little number. I did a few pulls with a wideband on both the dvr and pass side test pipe bungs, both A/F were pretty even. Here is a screen captured movie, sorry for the jerkiness, it's the capture software: may have to right click, save as datalogging video I didn't want to boost too much until I went on the dyno because every car is slightly different. If I had been driving around on 15 psi, I probably would have done damage. Either something was wrong, or my car is a little different for whatever reason. So...update to the group buy: 10% discount on all blazt usb, serial, and IPAQ pda cables, accepting payments starting today. If enough people join, 15% discount.
