does anyone know what is the max boost pressure which can give stock turbo ? i heard about 27.5 PSI,

At 7000' altitude I can get a 24PSI boost value with the engine at mid-range RPMs (4k or so). I have not tried at a lower altitude. The boost also tapers off at higher RPM; I see 18PSI at 7000' elevation at the redline.

These numbers are with EC P2 tune installed. I saw about 21PSI max stock.

All values reported by OBD2AA via torque via a bluetooth ELM adapter.

I think what he is saying is why spend big $$$ on big modifications on a 2.0 when you can buy a (discounted) QV and keep it stock and still have more power/warranty/aero/race mode/etc etc.

It will always be less expensive to play with 2.0L and if you want AWD like mine no QV available

I drive my Giulia on my long distance once a week commute. A bicycle is not practical for long distance travel.

I road my bicycle to work Tuesday, Wednesday and Thursday this week. It is an efficient, healthy and clean way to get to work, plus unlike a car I can afford a full on race machine. I find no joy in driving in traffic and do not see any justification for racing from stop light to stop light.

Of course if you are building a dedicated track car from a Giulia, more power to you. It is an appropriate way to show off that you know how to maximize the performance of a car and drive it. OTOH, I think some tracks today will not let you run cat-less even on the track.

Get a Geo or a Prius.

Here in NY we are working on couple different turbo setups. Also a set of Pistons are in the makings at CP. Pistons to lower compression a bit and be lighter. Stock Pistons pretty heavy. We'll start dynoing in next month or so. Can't see why there wouldn't be a nice stage 2 or 3 set up for having somewhat safe 400whp deal. I'll post some dynosheets as soon as we are done 👊

It's from focus RS 2.3 ecoboost.
But there is problem with intake temp. It's very high.

I think we need to change water cooler on front.

Are you using the stock IAT numbers or did you add a sensor? The stock IAT sensor is on the hot side of the intercooler.

I know that there is on hot, but it's still hot... now I changed tuner becuase my previous was piece of shit.
I will inform in 2-3weeks. I'm waiting in queue.
But I got info also that fuel is not enough. But all information will be after new tune.

Don't know about the Giulia, but on Stelivo, in MES the temp after the intercooler is "Air Temperature", the other one "Boost/Manifold" is the temperature before the cooler. How are you monitoring the temps? See attached images. The stats are taken after 10 minutes at speeds of the other photo.

I knew there had to be a proper iat sensor post ic. Unfortunately the generic pids used by jb4 and most scan tools are grabbing the pre ic iats. Thats what im displaying and logging and id love to not be

I think the post IC sensor is not exposed in the generic pids. As you can see the MES developers messed that up as well. I figured it out using wiTECH 2.0 and comparing. Also by logic, cause Air Temp goes up a bit on accel, but it cannot be MAF temp, because it is too high, and I figured it's post IC. After all I concluded the cooler, is more than adequate and it does not need upgrading for more aggresive tunes. Maybe a LC pump upgrade is more apropriate. Also keep in mind that NAFTA cars, have one less cooler (the lower drivers side front). Here in EU we have 2 small on each side and 2 big center coolers, so maybe that is also why I don't see the post IC temp as a limiting factor. Also keep in mind this is Stelvio not Giulia!

Youre a pioneer brother. Now if i could just find a way at it :) nice to know there are potentially some euro heat exchanger plug and play upgrades then too if necessary.
