595 Comp Boost fluctuating
« on: May 04, 2021, 12:09:17 pm »
Hello all!
Recently joined your great Forum, hoping some of you knowledgeable people will be able to assist with my problem!
I have a 2019 Competizione, recently ive noticed while accelerating hard in 4th or 5th gear, the boost builds fine but as the revs start to rise the boost fluctuates, like the revs are retarding/holding back!
Checked all vacuum lines etc and there doesnt appear to be any leaks.
Is it probable tht its the Boost solenoid?
Car is a 2019 with 13k on the clock, freshly serviced with new Plugs too.
Really dont have the time to take it to an Abarth dealership as i know its still under warranty but thought i’d ask you guys on here

    Welcome Farky77 :wave:

    Your problem could be caused by numerous faults.

    Are you over revving to the limiter?
    Engine in limp mode because of fault codes in ecu for example.
    Turbo waste gate faulty

    Do you have a scan tool to monitor any fault codes?

    Maybe a trip to an Abarth dealer is required.

    Been on a reader with no Fault Codes.
    Have the new 3 channel Bluespark on the Car, the issue was there prior to it however slightly different. Before the Box was put on, i noticed/felt the boost fluctuating in 4th or 5th gear when under full load/boost, didnt do it all the time tho and could reach max revs no problem.
    After the Box was fitted, it now holds back, retards the revs after 4-4.5k rpm amd struggles to Rev out? Accelerates hard in lower gears, easily nearing rev range. Only holds back revs, boost fluctuates when driven hard in mostly 4th & 5th gear.
    Hope tht all makes sense

    I would remove the Bluespark and take it back to the Abarth dealer as there appears to be an intermittent boost problem.

    But a word with Bluespark may not go amiss.  :thumb:
