How true. I took my car to a tuner after some research and spent a fair bit of money and my mates took the piss no end cos I'd spent 2k on a setup and some mechanics whereas they'd paid 120 quid for 2 hours on a dyno. 3 years later mines still pulling strong after a much cheaper checkup at the same place and one friend doesn't even have a ford anymore and the other has had about 5 turbo engines in that time. Enough said
