Hello Votech, i have just fitted the VS late last night.. i managed to drive it for a while and these are what i found
1. my stock factory 9 year old audio. slightly more efficient. lower level of volume needed to rpoduce the same amount of volume and slightly clearer.
2. air cond cold...this i am not sure as before this my air-cond already very vey cold. need a few dasy in the afternoon to test.
3. engine starting slightly crisper. i think less 1 or 2 cranks for the engine to start.
4. auto gearbox ....din notice much but maybe because i just changed the filter,oil and serviced it yesterday as well.
i now need to find a proper placee to mount it. it is just sitting on top of the battery now.
