Actually a full flash tune is far cheaper than this Dinan Stg1 while being superior in every way. This coming from somebody who owns a Dinan B58 tuner...
Please provide links that show gains 2-3X that of a piggyback... so like 120-180 hp? Or just links that show comparisons please, I have been trying to figure out which route I should go.
