24lbs injectors and crower 15511 on speed density

[Unit 5302]

I had a friend who ran 24lb/hr injectors on his stock 87GT. The 24s were cheaper than the 19s at the time. He had no issues with the change, and he was running the stock fuel pressure regulator, which is actually set at 39psi.

I don't have nearly the confidence in my hunches that gtsr has. If it's running good, and you have no drivability issues, I'd probably keep it like it is for a while. That TPS voltage is a little high though. What's it idle at?
