30th Aug 12 Hi Andrew, I purchased a Red power system from you last week for my Vauxhall Insignia ecoflex, I must admit I was a bit sceptic about your claims as I have purchased so called tuning items before & none of them worked (they were much cheaper than the red power system). Well all I can say is WOW the Red Power System has completely transformed my car, it is now more lively & the engine is much smoother, also my main problem was slow throttle response at low revs, this has now completely been eliminated, I had taken the car to a Vauxhall main dealer on three occasions regarding the slow throttle response but they failed to cure the problem even after carrying out a software upgrade, by the way if you have had your ecu remapped a software upgrade wipes the remap from the ECU. Many thanks Neil W Basingstoke.
