The Greddy blue will run your 1 bar set up spot on when you have it mapped but it will not remove the speed limiter you will either need an sld speed limit defencer or a mph convertor which attatches to your gearbox.
Shit to hear obviously your peed off to say the least but it's nobody else's fault but yours to put it blunt, if your skint you could break it in the breakers yard to get money back or find another engine!
Apparently Emb does not eliminate speed cut lol unsure about emu not that I'm planning on doing crazy speeds but if Y our packing 300bhp you want to get to 120 at least well it's nice to know you could.
X2 it's the small things that make the big difference, it's the whole thing of finding something that nobody else has some people appreciate things more than others Sam
