WRX STi Hard Start

Hard start on my subaru EJ207 (jdm v7).
Current (air related) mods:

- Apexi Short ram intake
- Perrin turbo inlet tube
- APS SR40 turbo
- APS up pipe
- HKS down pipe
- Greddy RS BOV (recirculated)
- Greddy FMIC

Only starts like this on a cold start. Any tips?

Are those 52mm or 60mm and what brand is your boost gauge

@bloodraing - 60mm defi

I no longer have this subie :(

The problem was a pre intake / turbo air leak I believe - was a long time ago. It was always professionally tuned to match my mods.

Whered you get i would like to buy that kind

[bloodraing]

Oh what brand is your boost gauge?

When I first got my new tune it did this for a little while while it was learning. It eventually went away.

My buddies Camaro also did this and it was the battery so Id say its one of those tow issues.

Hey man did you figure out your issue? My 93 Jdm just started doing this after I changed my turbo to a new oem one.
