alexander72 Posted June 28, 2014 Share Posted June 28, 2014 They were stretched - £18 on cables and I gained about 64 bhp and 2,600 revs :-) Quote Link to comment Share on other sites More sharing options...
Fordboi Posted June 29, 2014 Author Share Posted June 29, 2014 Awesome! Best £ per bhp mod I've heard of! So were the butterflys just not opening fully? Just checked mine and they open fully at full throttle. I was slightly disappointed actually! Quote Link to comment Share on other sites More sharing options...
