GT 02-Optimizer

GuzziTech proudly offers 02-optimizers

Ours work as advertised for most all Guzzi with 02-sensors, including big block CARC Guzzis. Does NOT work for '13-current V7 models. If your big block Guzzi has two 02-sensors stock, then you would need to purchase two (2) 02-Optimizers. If so, seriously consider our GT-Rx® ECU Flash Services. After you place your order, we will contact you for model info. Questions? Contact us via the tab above, Live Chat below, or direct email; Info at
