Why is my car so damn slow?

Hello everyone



I seem to be at a loss with my ZS 1.8L petrol, i have done a few mods to the engine as listed below:



Remap (z and f)

TF 135 inlet and injectors

TF 135 cams + vernier pulleys set to optimal values

52mm Throttle body

Stainless steel cat back + hollowed out maniverter

ITG foam filter located in the inner arch with cold air feed



Now with all these expencive goodies on board, you would expect some sort of performance? well youd be wrong



It is slow, incredibly, terrifyingly, outdragged by a people carrier slow, my works citroen van is faster in a streight line and iam beginning to think that something is wrong with the ZS, however there are no other issues, the car runs fine, retains good MPG, no idling problems or management lights, no emissions problems and no nasty noises or bad smells, does not use oil or water and generally runs spot on, but just incredibly slowly!



Anyone got any clues? is there something iam missing here?



Many thanks



Roo
