My Alfa Romeo has a boost issue. As you can see in the video, it has very poor response and boost below 2000 rpm. Then boost will build, but will fluctuate until about 3000 rpm where it will be more stable. When it’s cold, it has very low power/response. Taking off on a hill is almost...

Hi All, has anyone fitted the giulietta diesel intercooler to a QV? Looks like direct replacement and approximately 25% increase. beforebi drop 500 euros on an MTD and kit, thought I’d check if an $80 used diesel part might be worthwhile instead.

Hi There, I have a Giuietta MultiAir 170hp that is having some boost issues. I've tried a few things, but I've finally found something clearly wrong. The boost solenoid is connected to the wastegate actuator, the intake just past the air filter, and the final hose is a bit mangled and goes...

Hey guy I have 1.75 T 2012 giulietta qv How much ho can the engine handle on stock internals? How much boost the turbo can handle, and if I want to go over the max hp on stock internals what do I need to upgrade first? Thanks

Hi guys, I'm having an issue with my giulietta 2.0. Randomly one day I was making no boost. No error codes or anything. Then from time to time it builds boost but loses it, almost in surges. Took the car to the garage and changed the turbo and actuator, but the problem is still the same. I've...

Hi! I have mito qv (2010) i have boost cut and fluctuation on high rpm. During full thorttle the boost going to peak... and... i hear PIISSTTT sound at dv. After going to high rpm (4500+rpm) boost begins to fluctuate (for example 20psi>12psi>18psi>14psi...) I'm using MES and torque pro with...

when coming off a round about there seems to be a lack of low down boost, sluggishness. once it's up to speed it drives normally when you put your foot down. also when sat idling, you hit the throttle and the boost needle doesn't shoot up until you're revving it quite high. i've had the egr...

Hi guys, I've got a 2007 147 JTDm that I've had for a little over 6 months. The car has always been difficult to start but never had any engine fault lights come on. Go figure I finally sell the car and the same night I sell it the buyer says the engine light came on. Sure enough it did. Took...

Hello fellow alfa lovers (and haters :D) :) I disabled egr by editing ecu software by egr hysteresis, so egr is now not in use. But car still slow and crappy at 1,2 gear at revs lower then 3000rpm. So i opened EGR map and made change that ecu always gets max air quantity so it wont count on...

Hey Guys! I have red the whole internet literally and still can't find a solution to my strange problem. Not just Alfa but Opel-Vauxhall, Saab and other forums that share this engine. 147 1.9JTD 16V 2003 with 140hp 192A5.000 engine code. So, the problem is the following. The car under load...

Good morning All So my 159 2.4 jtdm ti has lost boost, no error codes. And car is not in limp mode? Any help would be good. Car is only out of the garage from my last post. Have had the boost control valve changed and and egr delete and swirl flaps done. Was running well then boost just dropped...

I own 156 2.4JTD 150hp SW 2002 which is only inside face ( if that matters) and i got ot remapped. The fuel adjustment is as much as possible to the point where I would need to upgrade the fuel system, else it will start cutting off cuz of not enough fuel. The turbo has been set to 1.2 bar, it...

So I had a problem with my 147 JTD 16v 140hp. The standard "MSCF failure" follows with limp home mode. The problem only occurred during full power acceleration in 4th,5th or 6th gear. Some times it happened and some times not. If it did not happen I could feel some steppines in the acceleration...

So I’ve a newish turbo fitted, I’m getting sporadic over boost issues. I’m suspecting a vac leak. I have to hand the old wastegate. Can anyone talk me through checking the vac hoses. I have a mity vac, but modern cars are a bit of a mystery...

Hi everyone, New here! Since Saturday I am the proud owner of a 2010 GQV Turbo lag/boost threshold is the only negative thing that has struck me. In 2nd gear nothing much seems to happen until around 3000 RPM. Is this normal for this generation GQV? I would have expected it to kick in around...

Yesterday I went out in my 147 and thought it didn't feel right then when I put my foot down a bit it was totally flat and the Eml came on. Scanned and I get p0238 code for boost sensor A circuit high. Its the 120bhp 8v jtd. I swapped the map sensor out my saab in and no difference. I was poking...

Hello, i am new to forum but not new to Alfa romeo driving. I am from Bulgaria so please excuse me for possibly bad english ! So here is my story... Recently i went to a person for a ECU remap. Before that he made a diagnostic and tell me that the turbo is overboosting. On the dashboard the...

Hi Guys, May i kindly ask you to provide me with % of boost solenoid at idle for 1.6 mjet or 2.0mjet? As, on idle when engine is hot the rod never touch stop screw and MES is showing 62% for solenoid. Is this ok or it should touch the screw? I am asking couse at low rpm car feels little laggy...

Hello guys, my Alfa GT doesn't pull until 2k RPM, then it goes like crazy. I logged my car yesterday with MES 4.3. It was dynamic test: 4th gear, 1,5k RPM full throttle up to 4k RPM. I'm attaching logs beneath. I think that my car fuel usage is kinda high. Recently I have driven 230km (170...

I was wondering if anyone else has suffered from this or knows what it might be? When I drive my 2.4 (210) hard it revs upto about 3500 revs and then flat spots. My swirl flaps are leaking a bit but this seems more than that? I have a hybrid turbo. Any ideas?? Thanks
