 Trustindex verifies that the original source of the review is Google. Went to southwest remapping after buying C4 Picasso with stage 1 plus remap. They checked car and found original remap not carried out correctly, and did stage 1 remap. Now MORE power and 20% MORE fuel economy 11 out of 10 Aaron

 Trustindex verifies that the original source of the review is Google. What a relief to find southwest remapping /Aaron. Fast, friendly, professional, competent and reasonably priced. An Engine update by VW, robbed my Golf Gtd of power, drastically increased my fuel consumption and caused 2 years of dpf / egr / CEL faults. VW, another “engine tuner” and a dpf specialist, all ignored what I was telling them, failed, multiple times, to diagnose the faults and charged a small fortune for being subjected to their incompetence.
Southwest remapping fixed the faults on the very first visit, increased my fuel efficiency by approx 15%, made my car substantially faster throughout the rev range and 6th gear pull / torque is incredible. And all for less than the others charged.
Thank you. I’m absolutely delighted with the results
