cheers maydew
with the mods is it a massive difference with performance over the standard spec, i know it sounds stupid but i dont wanna overstep the line of easy everyday use, what im saying is i dont want an undriveable monster if u get my drift
cheers

difference is night and day,but you soon get the itch and want more lol lol ,at that power the car will drive alot better as a daily user and better on fuel than standard well mine was lol it will rev alot more free. for 800quidish for everything its the biggest jump you will get for your buck,next step will cost alot more i.e turbo headers etc etc
get it mapped by zen or andy f and , it wont be a waste of money by far

You'll notice a pretty big difference in torque, i had my ppp kit remapped and it was a big difference. So going from standard straight to that will be something else again. I think the power level you'll end up with is spot on for everyday use.

so many asking this question 2nite lmao..... despite what alot say stick with a decatted 2.5" unless you intend on going for big power 400+(on a built engine) as all you will do with a 3" is make the car louder and maybe less responsive on a standard engine

du what i have just done. go for a 3" system uprated fuel pump filter and 3 port boost solinoid + remap. if the ninga back box and centre section is 2.5" sell it n get a full 3" system
