I would be suspicious of this!  There is a world of difference between a carefully developed, well-written chip, literally on an EPROM chip, where you have to (just as I did on my Alfa-Romeo 75 TwinSpark 2litre) un-plug and remove the ECU from the car, open it up, take out the original chip, and insert the new and improved chip, re-assemble the ECU and return it to the car, and these wonderful bull-shine devices which are nothing more than a dollars' worth of a resistor in a box, which simply tell your fuel-injection system to stay in 'choke' mode, meaning the system floods more fuel and less air into the engine, ultimately washing the oil out of the bores (causing vastly accellerated engine wear) with an excess of petrol, all the while wasting fuel!  The fact that this is fitted in a couple of minutes with velcro... it's a lot to pay for a dollars' worth of resistor, and not a good idea at all.

    Oh, BTW, my Alfa had 152bhp in standard form, I have added a K+N air-filter, which made the car livelier,a much better tubular exhaust manifold and adapted system, and now the chip into the ECU, which raises the rev-limiter from 6200rpm to 7500!  Power is up by 15% which is about 22bhp, and torque is up to, the big "hole" in the torque-curve at 2500-3000 rpm has just gone, the car is much more docile and driveable in town, and show it a little throttle, and feel the clean and instant pick-up.  Well worth it, and it was only about 45pounds from Germany, found on eBay.

     A small but effective Eaton supercharger is next, which should give me a solid 70bhp more, running at 7psi boost.
