Yesterday I installed 2013 injectors in place of my stock '07 injectors because my FP and injector duty cycles are way too high. If you've ever wondered how much head room 2013 injectors will give you, here is my data:
Stock Injectors:
4,000 rpm: injector duty cycle 68.7%; FP duty cycle 71.8%
5,000 rpm: injector duty cycle 84.1%; FP duty cycle 82.0%
6,000 rpm: injector duty cycle 97.1%; FP duty cycle 96.2%
6,200 rpm: injector duty cycle 99.1%; FP duty cycle 98.7%
2013 Injectors:
4,000 rpm: injector duty cycle - 66.9%; FP duty cycle 72.3%
5,000 rpm: injector duty cycle 79.1%; FP duty cycle 80.0%
6,000 rpm: injector duty cycle 94.3%; FP duty cycle 91.3%
6,200 rpm: injector duty cycle 94.0%; FP duty cycle 91.4%
Keep in mind, this is just with an initial tune that is running very rich (11.0 AFR) at WOT. Once tweaked, the numbers will come down a tad. The tune with the stock injectors is after remote tuning on a chassis dyno and multiple revisions. End result is that while I expected a tad more, after a tune revision I should be fine - particularly since it is as cold as it is ever going to get in Houston. In warmer weather, I'll have plenty of head room. I hope this info is helpful.
Seteup is 2013 TVS, 2.39" upper, 123mm CAI, 63.5 TB, 17.5V BAP, and axle backs. It makes around 625-640 hp depending on the day its on the dyno.
