I have them, Changed from ID2000's as they blocked up when the car was idle for 12months(E85). I should have pickled them in WD40...lesson learned. These fuse/rust together as they are disc type.
Idle of 14.7 AFR is easy to acheived with ID1300's on my 2ltr with pulse widths under 1.5msec. They are easily the best injector I have tuned. Having sad that I don't overly like the 5 degree spray pattern. Not great for E85 atomisation for good cold starts. Apples vs apples though they are the best injector in there size range bar none.
