0-60 will improve massively. No remapped (or stock) PD130 will be wheel spinning up to 60mph. Launching cleanly will be come more difficult but you will definitely see an improvement.
180hp is attainable with improved breathing and a fairly aggressive map. My old PD130 made 182hp and 342 lb/ft on R Tech's rollers, but it chewed through stock clutches every 12 months
Stock sidemount is shockingly poor and one of the best mods you can do is a front mount intercooler. Stay away from the uprated sidemount intercoolers - apart from being shiny they do very little in terms of improved cooling and in some cases (depending on fitment) can be worse than the standard cooler.
A generic remap will see you at a realistic 165-170hp
My 170bhp FR used to wheel spin??
