HKS Cams and SAFC Tuning Help

[turbospyder19]

I had my car dyno-tuned with the setup in my profile BEFORE cams. Last week I installed the cams, HKS 264/272. Now I know I need to re-tune the SAFC, but what exactly am I tuning for? What should I be paying attention to? Should I just go about tuning it the same way I did the base tune when I first installed the SAFC? I guess what I'm asking is, what did the cams change that needs to be tuned with the SAFC? Thanks for any help!

Do you have a datalogger?

Yea, I've got the OBDII PocketLogger.

My Throttle points are set to 1k, 1.6k, 2k, 3k, 3.6k, 4k, 4.6k, 5k, 5.6k, 6k, 6.6k, 7k. All of my Lo Throttle points were at -12% BEFORE cams. We just re-adjusted and came out with -8, -7, -4, -6, -6, -6, -6, -6, -6, -6, -6, -6. How do these sound for having just installed cams? I haven't adjusted them for the cams yet, but my Hi Throttle points are -15, -17, -19, -22, -26, -30, -33, -35, -37, -38, -39, -39. How much of a change should we expect when tuning Hi Throttle?

That sounds way off for the low throttle, what is our base fuel pressure? The setting should be pretty similar between low and high throttle. Do you have a hacked air sensor? WHat are your fuel trims?

Keep in mind, those Hi Throttle points I supplied are before tuning, I haven't been able to take it out to tune those yet. For the Lo Throttle we tuned the fuel trims to be as close to 0% as possible (because it's a 2G). My MAF is not hacked and I don't have a fuel pressure regulator, stock pressure.
