Rover 200 sdi tuning

Hi all,



Decided to do an overhaul today with my diesel.



It was running a remap and was very Smokey sometimes.



I've gone back to basics and returned the tuning side of things to standard and start again.



Stock fuel chip - goes ok but considerably slower compared to the chip it had.



Next I connected up the synergy vp, and set it to low/medium with the fuelling dial almost at max.



The car isn't that much quicker than standard which has me puzzled.



There is no smoke either.



The lead is connected properly and you can feel it pull a bit harder after 2k.



Have I done something wrong or am I just used to the aggressive chip I've had?



Thanks
