was the emperors clothes or a dud.

there are no dyno print outs anywhere.

i rang novitech and they said they stopped making it and they only ever fitted one.

no workshop that i contacted that you see in the youtube videos responded when i emailed them asking about it.

then this guy who is a bit of a god among men in the aston specialist world (worked in astons engine development) explains why the SC kit for the vantage doesnt work and is a waste of time on the v8 4.2 - 4.7 due to the compression ratio being to high. The f136 maserati engine has an even higher compression ratio

very interesting video if you want to watch the whole thing if not the interesting bit is here..
