The Jeep 2.0 GME is not the same as the Alfa 2.0 GME. A simple look under the hood shows that the Jeep is DOHC while the Alfa is SOHC. This means that the heads are different, the cam drive is different, the VVT is different, etc. etc.
The block differences are explained here...
The turbo is liquid-cooled, and an electric circulating pump runs after the engine is shut off to lower the temp (this pump can be heard if parked in a quiet garage). This isnāt the 20th century anymore, no need to idle for five minutes before shutting off the turbo engine.

Sadly there is little value here. No reliable repeatable data on mpg or hp differences. One or two vehicles doesnāt prove anything. People will usually resort to conformational bias anyway regardless of any āproofā offered. Just like vehicle break-in and oil changes, everyone knows what is...
Maybe here. Yes I know itās a pic of a JK, but the same thing should be available soon for the JL. Iāve used gauge pods like this on other vehicles, it provides a clean install, not in the way but easy to see.
So he should fly >1500 miles twice a month just to āstart it upā? [Heās a snowbird so he wonāt be in the same part of the country.] He should be fine, just run the Jeep a few miles after adding the stabilizer to insure itās distributed throughout the fueling system.

LOL. I donāt know what to tell you, mine shows a positive 8 psi at idle, when I advance the throttle the value increases, it does not drop to zero then increase. This instrument is reading the MAP sensor, the PCM needs to know that value to control the engine at different altitudes and...
Remember that the Alfa 2.0 engine is entirely different from the Jeep 2.0, so researching the two engines is hardly a direct comparison. They had different design teams, completely different heads, different VVT, completely different blocks, different tuning, etc. They do share the same...
Anything over 120 lbs wouldnāt be a very desirable wench.
Adding weight to any vehicle anywhere will degrade its performance, it increases the lb/hp ratio and the vehicle will accelerate more slowly and use more fuel to do it. The same reason toting an extra 500 lbs of people and gear slows...
Believe whatever you want, but what does it read at idle? If it doesn't measure atmospheric, then you should see a negative value...vacuum. But you donāt, instead you see ~8 psi. Subtract atmospheric pressure and you are at 6 psi of vacuum...normal for idle.
Actually it ācanā hurt, if you don't like getting a CEL. Some report getting the light, others donāt. As for value, to me it is in the same area as the āgrounding wireā fad from a decade ago. I change oil every 5000 miles, and I see no change in oil level over that time period. So, where...
Because that is not the boost pressure. The OBD2 reads MAP, not boost. You have to subtract atmospheric pressure, which is ~14.7 psi depending on DA. Your actual boost is about 10 psi. The gauge doesnāt depict fractions of a psi.

The 2.0 redline is well below the 6000 rpm shown on the JL tach, about 5600 in fact. The tach redline is puzzling, the same engine in the Cherokee has a different redline, see below.
FWIW, the completely different FCA 2.0 in the Alfa also has the same lower redline on the tach, see below.
A roots type blower gives instant boost and power regardless of rpm because it is a positive displacement compressor. I know, Iāve owned three. A centrifugal blower does require a minimum rpm to develop usable boost, at low rpm it produces little. I know, I've owned one. The turbocharger...
You realize that this is not true, right? You can use lower octane in the 2.0, lots of posts here about that. There is a performance advantage to 91 octane but for highway driving, little to no mpg difference. I use 91 only, but many use 87 or 89.
He wants to be able to drive to his home rather that walk to it. In his experience the hardware difference on the Rubi is essential. Thatās why.
Yeah, all that electronic sh** is unreliable, he should just buy a new 1980 CJ-5. No fancy stuff there.......analog baby!

Yes, it could. My ā15 Challengerās injectors made the clicking noise when cold and the frequency increased as the rpm rose, although I havenāt heard it on the 2.0.
