you should start by getting rid of that blow off valve. you are purging metered air that the engine is compensating for.

Ditch the BOV and it will behave better. There is a link in my sig which gives more detail. Two Step Performance and Phearable are behind the most popular off the shelf tunes available. Give them a look.

Many intakes are known to skew the MAF readings. You should switch back to the stock intake or pick up a PRL or other "known good" intake.

Seems like someone has been throwing more dollars than sense at your car.

The MAF housing is slightly oversized and require custom tuning for proper operation.

MAP states the following: Please Note: This wIll work on a stock vehicle, but if tuned the MAP Stage 1+ Tune is required.

I assume you are not using their tune? No other "off the shelf" tune is designed to work with that intake.

Intake might be ok, swapping the stock intake back to see if the issues remain could help figure it out. First thing for sure though is to ditch the BOV.

Ok I’m using the ktuner 19-23psi tune

So as someone stated above, in order to use the MAP intake, you would need to use the MAP tune. Based off what you currently have on the car, you should probably be getting a custom tune and that would negate the need to run the MAP tune since the custom tune will be specific to what you have installed currently.

and ditch the bov.

If you can, get some before and after dynos lol.

Consider adding your car to my community tuning thread and like others have said, ditch the BOV.

Will try not many synod near me

Getting before and after dyno's is kind of expensive and time consuming once you've already modded. Generally you would establish a stock/baseline dyno, then periodically get new dyno runs in with each modification. That's what I did back when I had my WRX, but I was single and had a lot of disposable income as well as free time. Easily had a dozen dyno tuning sessions over the course of 6 years.

Putting a car on the dyno is a good recommendation, but overall just get some tuning time spent on the car.

I know it isn't the cheapest thing to do lol. That's why I said if you can. I am just curious to see how much is gained going from the Ktuner tune to a custom tune with his current setup. Minus the BOV ?
