ah, my mate alan. he once signed up her to try and make me sound stupid after he LOST my rather rare peice of turbotechnics equipment and didn't care

basically, whilst what youve told s not FACT, hes advising you to change the spec of your car so that HE kws what to do with it. there are many competent tuners in the UK who can deal with the standard cosse stuff just fine, so you do not NEED to change anytihng (otehr than your tuner )
