I got a 2014 gti 155 ltd last year (there werent any gtr 215s available in my area and i got the gti at a good price since the dealer owner had used it for 3 hours). I actually really like my ski but as always would like to get the most out of it. Is this kit actually going to help the ski achieve higher outputs/speed or is this one of those 'make me think its actually doing better' things?
