Mine is around 400 or so, no bogging no stalling. I am also doing this on a fully built block, running a 16G...

I will list all mods/electrical below. I changed the spark plugs about 15k ago to the factory NGK set so im not sure about those but are still in good shape. They are gapped at .028. This started about a month or two ago Thanks for any insight.

PS I am thinking that it could be the ground on the in dash unit but not sure if that would make it dip way down.

On your Cobb unit under tuning, have you raised the idle there? Mine is at 600 after my new motor with upgrades and I raise mine using the tuning feature!

Maybe you need a coolant/thermostat change? What does your gauge say when you are at idle? Dead center?

Or maybe you just need to clean the Idle Air Control Valve - IACV - it's super easy, get a new gasket for $4, some Q-Tips, and maybe a bottle of Seafoam for $6 and clean that sucker. Did the trick for me.
I have the IACV gasket already. I will do that and also change the coolant. Never done it.

My idle reads -11 i think it is high. Most people get around -20

Its commin with boxer motors to idle lower than other car especially When in traffic. You can use the Cobb access port To adjust the timing

Hello, so i am having a very similar issue i have a 04 WRX JDM ej205, CAI, TGV Deletes, 1000cc Injectors, Td05 B16g Turbo,COBB EBCS, DW300 Fuel Pump, Tuned by IATUNING, Downpipe, Uppipe. Whenever i try to get on it and go WOT it studders. I have tried adjusting wastegate actuator. Seems like its not getting enough fuel. I just recently installed the Fuel pump, Injectors, And Td05, aswell as TGv Deletes. seems to do it at around 11.9Lbs of Boost. Any ideas?

I recently pulled my engine and replaced the rear main seal and a new lightened flywheel with stage 2 clutch. At idle it is almost dying completely and throwing misfire CELs. My question is, is anybody having this trouble after install of lightened flywheel? I am thinking about putting back the stock flywheel and trying my luck... any info helps, thanks in advance.
