I can assure you the PC will fix the surging but it�s a jigsaw puzzle and you need all the pieces,thats a pair of aftermarket pipes,snorkel out,both 1&2 filters and the holes as per the size in the air box it will transform the bike,leave anyone one of those mods out and you�ll notice the difference with the bike I did each one separately.

I originally went the Kev mod there�s a marked improvement and you�ll get the same improvement again from his mod to a PC just a case of how much you want to spend and how much hassle you want to go through to get that better result.
