Need for a tune after HKS SSQV BoV install ?
Hi folks, generally new to the forum, I have a new shape 2014 STI completely stock, been waiting to pull the trigger on a HKS SSQV BoV (http://scoobyworld.co.uk/catalog/pro...oducts_id=1237) along with an Invidia R400 cat-back.
I've heard two sides of the argument that you need a tune after a BoV install because of MAF readings, creating rich and lean conditions which the ECU tries to counter, resulting in pops and bangs.
So is it safe enough to run a BoV stock tune as PSi I'm running is stock, or do I need a tune also ? If I've missed a forum discussion on this topic let me know.
Thanks in advance

If you are just fitting the BOV you will be fine.
The miniscule amount of affect on the AFR`s to your mpg will be the same as acclerating quickly that 1 extra time off the lights

The Invidia R400 cat-back is a more free flowing exhaust compared to stock, you wont "need" a remap but, you may find the better exhaust actually hinders power a bit , maybe not noticable on the road though.

@BrownPantsRacing I believe there is an adapter from downpipe to 3" mid pipe available, I've researched around and people saying stock tune fine for exhaust, I'm curious if a catback and BoV would be enough to categorize a "Stage 1" remap. I know aftermarket intake and catback would be.
Again, open to advice and opinions

If I were you I'd get it mapped with the upgrades on anyhow, will transform the car. No point fitting these upgrade parts if you're not going to make the most of them with an ECU tweak.
Also worth upgrading the fuel pump.

Aftermarket intake is not "stage 1" tune. a typical "stage 1" tune will be an uprated panel filter not CAI system. You can run the standard airbox with an uprated filter happily up to 400bhp.

I’m not looking for upgraded performance or going into the whole Fuel pump, injectors route, just looking to bring out the Boxer rumble and a BoV.
But I do understand where your coming from because I’ve heard 2.5s don’t react well to the smallest of mods without a tune also, but also hearing other side of the story. I guess I might just do one at a time and see how the car reacts and then remap if necessary?

I wouldn’t be too sure on remapping from 300 to 400bhp with the only mod being a better filter

I was suggesting parts worth upgrading. There are sticky notes on this site that will help you greatly with upgrade paths. You would do well to look at these, they are very helpful indeed.

Ive fitted a 3inch system to a standard size downpipe using original conical gasket, springs and bolts. I made a 5 mm spacer ring to push the conical gasket forward. It is possible.

Have a look through this thread and read the tuning guide in the link, it's a great starting point.
