Was wondering if any of you guys would be willing to share what the max timing you've ever run is? Story is, I've been tuning a local 2.5 class pull truck. Setup is a Blacks 6.4, Turbo is a 96mm comp with a 2.5 insert, 103mm turbine, t6, 250% over injectors, twin cp3, one is a 12mm on one 10mm, 6.7 rail sensor. Anyhow I've been running it at 2250uS duration, 29k psi and 45* timing up top. It's made 820hp and 1280tq on a really stingy mustang dyno.
Looking at the logs it looks to me like it wants more timing, you can see the rpm rate of rise start to fall off with the timing curve, it follows it to the T. I've tuned a couple hundred trucks but not a lot like this and I'm a little nervous to give it anymore timing. I was hoping that one of you would be so kind as to give me a little insight. I appreciate the help.
Thanks,
Dominic
