    Boost problems / 99ron Tescos??

    Well ive been having some boost problems with my gsi mapped to phase 1 so ive changed the actuator to a vxr one set it up, Ive got new iridiums in and no boost leaks read bcs is bypassed, And still the boost is not smooth at all.

    So ive been on to Chris at Regal and he said that it could be the 99 ron tesco fuel i use he said dont use it, use only Shell v power.

    Im aslo getting a bit of turbo stall ie squeeling on full throttle in some gears mostly 5th.

    So im getting sick now and very close to getting a new turbo im still on my let one with 63k on the clock.

    Very much doubt it'l be related to fuel

    Have you changed the front boost solonoid?

    Define squealing? Doesn't sound like turbo stall

    It be good if you have someone local to you who can lend you a front bcs to try. Also a friend of mine had similar issues (although was a TT) turned out to be the maf sensor so might be worth checking that out to.

    No fault coes I'm presuming?

    have you had the actuator set up or have you just set it by threads?

    personally i would have the actuator settings checked as all are slightly different and then go off that, front bcs would be a good idea to change also.
