i can see problems with it.
25% more horsepower? really? if so why hasn't everyone got one?
other than that, it works by adjusting the signals to the ECU, so the ECU needs mapping to suit. without that mapping you're running the risk of leaning out (BANG!
) or running rich and losing power.
i'd say for the cost of buying and importing, you may as well buy a microtech (tublade had a mapped one for sale? it'd be cheaper)
