    Fuel cut

    So I oveboosted to bout 17.5 psi and hit fuel cut on my way from work. I turned the boost down and still getting fuel cut in 2nd,3rd,4th and 5th around 5k rpm. I am now only boosting .5 bar( around 7 psi) but I can still run all the way through first without problems. . I do have CEL but i havent had the codes pulled yet.(Cel has always been on as I havent put the resistor for the EGT in since my upipe mod last week)
    When it happened I immediately pulled over and reset the ECU and put the boost back to stock and still getting fuel cut in the same places Mods are TXS uppipe, 3 inch Home made bellmouth DP. Utec untuned( only installed untuned still using stock map, been very busy lately) Can anyone shed some light as to why im still getting fuel cut at stock boost levels?

    I'm having a similar problem. I don't know if I overboosted or not. One morning, I did redline. I didn't see any ill effect until a day or so later so I shrugged it off. I'm Cobb stage 1, get fuel cut (WOT), hesitation, stuttering (90% throttle), and won't boost over .5 MPa (90% throttle) myself.

    I've been researching the problem. If you're interested in what I find, check my post from time to time as I'm definitely going to update it with what I find.

    Stutter or stall under hard acceleration?

    More than meets the eye.
