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
