May question is, is this legit? kung legit man, may epekto kaya eto sa makina?
if your fort didn't need it before, why should it need it now?
my thoughts are, there's something wrong with your vehicle. fixing it right, instead of resorting to add-ons, is the correct way to go.

what's the problem? are you getting enough rpm, but no pull?
or, are you not getting enough rpm, hence the low pulling power?

errr...
how's the transmission, po? sliipping clutch discs..?
