advice on vito 111 cdi 04 plate

[t29sab]

hi i would like some advice on wether or not to upgrade the performance on my van in way of fitting a tunning box or getting it remapped as i am dissapointed with the standard performance and fuel economy , yes i know its a van but the flat spots through the acceleration range is pretty poor this the first time ive owned a mercedes and and i thought it would of gone a bit better than it does. milage 14k.

when was it last serviced? it shouldnt have flat sopts... also - try getting the codes reead by an indy - and getting a printout of them.

if all is well - then yes, there are tunign boixes which seem to be good (but are expensive)
