i am chilled, just informing him rather than get advice from a load of people who have prob never done it and pay silly cash he should do the reasearch and he will understand it soo much easier

you got to a tuner then hes gonna pay 1500 quid yeah, most will sell him cossie managment too saying its needed and frst aint as good blah blah blah

nobody who actually understands it will be willing to not only list the parts but expalin why he needs em and what he dont properly

do a little reasearch like what he should to and ask when hes confused on issues and he will do it faster imo

ive already told him about the CPS, told him what managment to use, the rest he can get from a haynes manual tbh and hes sorted
