advice on tuning HSR GTA?
I just put a stealth ram intake on my 88 GTA with #24 injectors, and I put a comp cams .464 lift cam in there with 222/226 duration. I also threw out my smog pump and all my emmissions junk and put on non emmissions headers. What are some things I should change in my prom? I am using an 89 bin with no cold start, tuner cat...also what fuel pressure would be the best to run?

Use the fuel pressure the injectors were rated at.
You'll need to change the timing and fueling to reflect the different engine characteristics. ie the peak torque and HP rpm levels have changed.
