12th Jun 13 Hi mate. Just an update on the corsa 1.7 with the crd-t box. Had it on 4 months now with no problems at all. After a bit of playing about its now on map 3+1 and the difference over the red box is amazing. Its alot smoother but pulls harder between 2-4k. Hopefully get it on a rolling road soon. Had it at santa pod at weekend running 15.5s @ 89mph which was about the same as a corsa vxr. Definately worth every penny.
