Well I'm running a modify ect with my AEM and if I'm moving it stays at 3 bars but in town it goes from 3-4 bars. Modifrys site says 3 bars is 190 the 4th comes on at 205. Not sure if I should worry or not. I may have to bleed the coolant again. I don't know what a safe range is.
1st bar - Below 160 (always on)
2nd bar - 160-175 (OK to VTEC)
3rd bar - 175-190 (normal)
4th bar - 190-205 (normal)
5th bar - 205-220 (hot)
6th bar - 220-235 (danger)
7th bar - Above 235 (shut it down)

I want to know what you find. I have the stock fpr as well and have the same problems you describe. Even partial load in lower gears at low rpms and my afr will dip into the high 11's. Same thing cruising in 6th.
I have also attempted to adjust my fuel table only to revert back to what it was before because nothing was helping. I even adjusted the o2 feedback as well only to revert for the same reason.
I don't know if it is the changes in temp (tuned when it was about 45 degrees outside) or the changes in my exhaust, but doing a pull my afr's will even drop down to the 10's especially in lower gears.
Edit; Fuel setup is...
Stock fpr
AEM 320 single pump
FID 1200cc's
stock lines and rail
2005 with return system

Hey guys. I have a quick question for you. I have a 60mm HKS hi-power that I ran on my car when it was NA.. I'm wondering if you guys have a ball-park thought of what the max wheel HP you'd get out of this exhaust is? Also, I'm wondering if having a restrictive exhaust can affect the boost you're able to make? I'm only making 9.6psi instead of 12 PSI (which is what my solenoid is set to) I'm just running the exhaust temporarily until I can get a 3" straight pipe to muffler installed.
Some info about my kit: pfab stage 2 with 5858 CEA-- 750 cc FID -- 340 lph pump.... Turbo has a 2.5" discharge that goes to a 3" downpipe/testpipe-- It currently reduces down to my 60MM HKS after the testpipe.

Has anyone ever had an Aeromotive 340 pump fail on them? On the dyno today we noticed a fuel pressure issue and it turned out to be my pump. Bummer cause now I have a Whineboro back in there (only thing they had handy to swap in).
