Shame I cannot put the video up but had the car on the rolling road today, lots of flames out of the back of the car on the over run

.
ended up as a nightmare like it always seems to

. car started to miss then would only run on 1-2 cylinders then not at all. after fitting new plugs, removing the injectors and having them tested (cost involved) back on the car and its just the same? it is my new power commander that is faulty unplugged it and all works a treat? car starts better made 12bhp more with it disconnected and guess what, i purchased it in the states to save some pennies and looking at the company they only give a 14 day money back guarantee even dynojet will not honour the warranty on it?
Oh and my battery then decided to stop working it has a bad connector from the pillar to the internal contact great.
