Apsoloute gives more bhp/torque for my 2.5tdi s80 and cheaper however they take the chip out from the ecu and reprogram it while the others are just plug in and reprogram without taking the ecu out. For me its between Upsoloute and Rica which would you choose and why.Thanks

£275 - Apsoloute
£470 -£500 Rica, Superchip
