VAUXHALL ZAFIRA GSI
“Took my Zafira gsi for a remap, as was running iffy on boost after I replaced everything in the world! They quickly identified it had had a diy map, even told me at what revs it played up at. Anyhow, they rewrote it, said I wouldn’t gain much more power, but it goes like a stabbed rat! For the money? Why pay £500? These guys are fantastic.
