So im running MS2 Seqential with 1000cc Injectors. Ive got it to idle decently, now im trying to use auto tune to help with tuning the VE table in the lower load areas. At idle 1000Rpm, it sits at about -18.5 inHg. as i slowly open the tb to like 1500 or 2200, i can see vac drop to -14in Hg. that seem normal, then as im sitting at that rpm (please not im driving so there is a load here) the vac drops to around ~ -22/23in hg. Tha doesnt seem right.. is is that normal?

Timing, timing/head is stock. heres my ignition table to see what numbers im pulling at given rpm vs in Hg,
