  1. Gen1 1.4L Turbo
    2013 Cruze with about 71k miles, and a while ago it started misfiring on acceleration. I found a faulty spark plug and changed the set. I did see a little oil on the plugs but I do not know how old they were, I got the car at about 60k. Anyway, I put new plugs in and the misfire seemed to go...

  3. Gen1 1.4L Turbo
    Hey everyone, a quick question. I've done a lot of repairs and maintenance on my '11 LT with 145K miles, and one thing that is driving me crazy is the boost. It does get up and go, but if I'm trying to accelerate on an incline, I can feel the boost engage and then let off some, and it's a...
  4. Gen 1 Tuning/Modifications
    The only reason I am starting this is because I plan on doing quite a few writeups in the coming future (two pretty detailed ones so far and two more to come), and it would be nice for those interested to be able to get a list in case they don't get stickied and/or lost in the forums. I have...
  5. Gen1 1.4L Turbo
    Hi, My boost used to drop from 22+psi to 15-16psi before 5000rpm and the torque followed the boost curve. Now with the new BNR WGA and retune the boost holds consistently over 21+psi over 6000rpm, but there is no more power top end. With the retune the stock injector duty cycle is up from...

    Items needed Psi gauge at least 20 psi 1/4” hose Air hose connector to air supply To test for boost leaks you will need a psi gauge that will test at least 20 psi and that you can read accurately. I used a “T” junction and 1/4” hose, and one of the 1/4 inch hose I slipped over the connective...
  8. Gen1 1.4L Turbo
    2014 1.4t AT. Stock. 72k miles. Ive read almost every single thread on here using the keyword "No Boost" but still dont think I found a similar situation. So the past 2 weeks I have found that when I hit the accelerate it is WAY under powered. I plugged in my ODB and using TorquePro I saw that...
  9. Gen1 1.4L Turbo
    Hi everyone!! So today I made my own boost leak tester and tried testing my 2014 Cruze for boost leaks. ( I got a P0299 code about 3 days ago. ) So today I hooked up my boost leak tester and regulated my compressor to 22 PSI and opened up the valve on my boost leak tester and slowly let...
  10. Gen1 1.4L Turbo
    The “Gen 1” 1.4L turbocharged engine (RPO:LUJ or LUV) can have some spectacular power gains from upgrading the OE turbocharger wastegate actuator, when combined with proper tuning! This article goes into how boost control works on these engines (and turbocharged engines in general) and...

I have owned it since July and bought it used as the second owner with 68,000 miles on it and completely stock. Since then I...
  15. General Discussion
    Hi, I have a BNR tune with nearly 23psi which starts dropping at 4000rpm and ends up at about 15psi. The stock wastegate actuator is on it's way out as it used to only drop to 17psi. My question is: Does the boost drop in high RPM only because of the weak stock actuator or is it because it's a...

    Hello fellow Cruze owners Under what conditions does the 1.4L engine initiate and use turbocharger boost? In a properly functioning engine, when is boost mode activated? Thanks in advance. Best Good
