    Is this normal?

    Ok on my 1.6 sxi so far ive done de-retricted airbox, aftermarket airfilter remus center section and magnex back-box and ive noticed that low down in the rev range it doesnt seem to pull as much when standard it feels like ive lost some power low down but when i hit 3,5000rpm-4000rpm it turns in to a beast! more power than when it was standard! Pulls alot harder. Its there anything i can do to improve the low down power?

    Why thank you

    You have gained abit of top end at teh sacrafice of torque.

    Its probaly only slightly more powerful or none atall because of the sound.
    You have maybe lost power and will of lost torque.

    Torque isint something you can really sacrafice in a 1.6

    Maybe put the standard back box on to improve lower down torque because therefore you will be gaining back pressure
