Im inclined to agree with you on that Stupra although i can get a Viezu Vswitch for less that a Bluefin with a slightly igher BHP increase from Viezu . I have a friends that has a franchise with Viezu to but unless i stick it on any rolling oad i will never know the exact increase i get from any re map. When we sell our 54 plate Tigra i think ill get it done
