could bad gas cause this?

[spools420a]

The story is I bought a sr20det 240 coupe and its been sitting while I buy more parts for it,The setup is pretty much stock ie,.

redtop sr
walbro 255lph
greddy fmic
electric fan
hks downpipe
little buddy club battery

other then that its stock
I check the plugs and all have the white tips,The car runs just fine but the gas is almost 4 months old,Also the gap was at 0.40 which was a huge gap which should be around 0.28,The cars been running 7 psi boost since I bought it and I have no wideband to monitor afr at the moment,I know the white usually meens heat/lean but I'm wondering if old gas could play a roll in this?Timing is stock still havent checked fuel pressure but I'll do it tomarrow.Everything seems good but the plugs make me worried.

The plugs are BKR7E,Any input on what I should check next?Could the gap being that far off or bad gas cause this?Also noticed when I wired in the electric fans it seems to steal some of the fuel pumps power so maybe I should rewire the pump or ground it out better,seems like most things running on acc are taking some juice from the pump
