My one and only complaint about him is;
He tunes to conservatively and I witness'd first hand him lying about the ARF’s on a mates car tuned by someone else to try and get the business.
Being conservative is no doubt a good thing, the very last thing you want is a car to go bang on the dyno or some young kid having a cry a week later when he spins a big end, regaurdless when you have signed the disclaimer and have been instructed to get the most out of the car and refuse to, it is a little disappointing.
Other than that very knowledgeable man
