    Default Idling sound

    I have a genpu and it sounds like its a train. It chug chug chug at idle when its hot.

    I have octane 91 atm in the tank and there is no knocking/slapping coming from the engine bay.

    Any body else experience this?

    No warnings on dash. Chain was checked i think last month.

    This is my first ever DI car, and bought this last year October. So I have no idea what it supposed to sound like during summer months.

    I just put in esso 93. It just probably do not like petro 91. I used to put shell 91 but i was in the boonies last weekend.

    Ill make a clip tmrw and/or make one of you speed3 dudes at the bbq sit in my car and listen... or ill sit in the stock ones.

    I don't hear anything wrong. Open the engine bay and record from there. Sounds pretty normal to me.

    Nothing really sounds unusual to me, I am unable to compare to mine as it is a noisy car for other reasons

    Ultra94 shouldn't solve your problem and if it does you really have a problem

    did you reflash the 94 oct map as well? coz it wont really run any better 94 gas on 91 tune.

    Sounds normal to me. The DI of the engine sounds a bit different than normal. I hear all kinds of ticks which freaked me out at first.

    Your car has absorbed the spirit of Thomas the tank engine. Use this power for good.

    Well the chugging sound is still there on hot days regardless of what octane I use.

    Now at this point, im going to see jimmy thursday so an opinion.

    I don't hear anything wrong and to firm up what someone else was saying, 94 octane doesn't mean a damn thing if your car only needs 91. If you're knocking on 91, you have waaaay bigger problems.
