Idle RPM question

Where do your guy's cars idle at for cold start and then after warmed up. Since my recent mods(headers,catless UP+DP, walbro, MBC) it seems like my car idles crazy high.

Cold Start idle is around 1500-1600 RPM

Warmed up Idle is around 800-900 RPM

my car isn't tuned yet but according to Ed at EQ the AFR looked good(didnt tune because TD04 is on verge of death)

Is this normal for these mods? If not what could be the issue?

Im no tuner but I know you should be very careful with that setup because of boost spikes / creep. You run gauges right?

A tune could probably even it out.

My idle when warm is around 500. My cold idle is about the same as yours.

Cold idle is about 1200-1500 and warm is 750.

The line that most Subarus idle at is actually 750, not 500 like some people believe.

Gauges are on my list, right now I'm just running Wastegate boost(MBC all the way - ) because my turbo is on the way out.

You find one yet?

I can't get a number out of Blouch so I'm just gonna go with a stock one. Irritating.

Got one out of an 06 with 30k on it lined up... I keep thinking about going vf39,injects, intercooler , though. Kinda broke so I'll probably just go td04 again and wait to do the vf39 upgrade next year.

If you snag that one out of the 06 and decide you want to go vf39 drop me aline. I'll buy it off you.

I have a loaner from my buddy but I don't want to beat up his turbo.

I'm not looking to do anything upgrade wise to my motor anymore. I'll live with it and rock it as is until she goes. Then I'll go ape on my build and get exactly what I want. LOL!
