    A little more boost

    Hello people,

    is it possible to raise the boost "a little bit"?
    Maybe to 0,7 or 0,8 Bar...

    Hereīs my setup:
    -Stock Redtop
    -T25G
    -3" exhaust system
    -FMIC
    -air filter

    Is it okay to run a little more boost with the OEM map?

    thanks
    Alex

    In short, yes you can.

    Im running at 0.8bar currently but am limited due to stock wmic and on the stock map. However I believe it is possible to run slightly more boost with a fmic on stock map. I think you may get close to maxing out the injectors though.

    Dont quote me, but im sure the full metal gasket (Tim) is running just under 1 bar on the stock map

    Another worthwhile mod would be an uprated fuel pump too mate.

    My old one Run at 1bar with no problems. Wallace did say the injectors are almost maxxed and that I couldn't turn the boost up anymore.

    I also suggest you ask jez if it's mapped for t28. If it is, get one and you will then be running approx 280bhp as opposed to the 250bhp that a t25 will make. Another thing that let's the power down is the actuator. Buy a hks actuator or similar and set the boost with this and you will notice the power holding alot better at the top end of the revs.
