Check out "Project 135: Software" by Sam Du in Eurotuner's February issue. Du reviews GIAC's software flash upgrade on Eurotuner's 135i and reports "improvement in power, torque, throttle response and engine speed, [without] reduced fuel economy or a reduction in engine manners". Eurotuner's BMW 135i project car gained 41 whp and 51 lb-ft with the GIAC software upgrade over the stock programming. For the traditionally piggyback-dominated BMW software tuning market, the GIAC software flash means no visible alterations to the ECU and more power per dollar. GIAC's software for BMW 135, 335 and 535 applications is sold through GIAC authorized dealers at a MSRP of $800. Contact your local GIAC dealer for more information.
