    Default boost cut? fuel cut?

    hi all.

    have just had my DownPipe installed today and had a little fun on the way home.
    I hit what I think is either a fuel cut or a boost cut and am looking for your thoughts
    my mods are in my sig and im currently running a stage 1 cobb map (about to flash a stage 2 and buy a E-tune now)
    and I can hear what I think are the valves tapping away from inside the car is this because of the catless DP allowing more sound thru?

    thanks

    I'm SURE it's due to your mods. :s In all seriousness though, if you are on a stage 1 tune (16 psi?) it's probably boost cut as you are hitting almost 20psi. Etune should have you sorted out though

    Yeah, think you're hitting boost cut, hitting 19+ psi is too much for stage 1...

    I'd suggest a proper tune asap as you're also hitting low 12 AFR, your fuel trims are off by a bit...

    and i have an issue with the base of the downpipe resting on the firewall and bar underneath the driver seat. ways to reolve this? beat the firewall with a mallet and remove the bar? or is there other methods that you fellas have come across?

    and @Lachlan im getting rid of this sure shit asap....just gotta recover from the moneys i spent on pipe+install and tune

    Ha ha, I was just kidding @kiwi If you do upgrade though, definitely recommend at least a 3" intake to make the most of the tune.
