sr20det no power below 2,500rpm!!!!

Hi guys I Have a s13 sr20det in my s13 and im having some problems. I have a garrett gt2876r .64 only runing 8lbs,nismo 740cc injectors, hks step1 cams, greddy intake manifold, z32 maf, enthalpy tune etc...etc. Well when i drive the car if i let the rpms go below 2,500 and if you give it any kind of throttle the car will bog and buck and almost die. It has no power below 2,500 but after 2,500 it runs fine and has a shit load of power. It does the same thing if you rev it up with it in neutral except that it hesitates a little then after 2500 revs fast
I checked
timing
maf
fuel pump
Im getting spark on all coils
im getting tons of fuel
fuel pressure is good
spark plugs gapped at .028
no boost leak or vacuum leak
compression is good
no codes
Im thinking that its getting to much fuel below 2500 so thats why it bogs but im not 100% sure. I just ordered a safc and a wideband. Please let me know if you have any ideas on what it could be.
