Mail order calibrations are the result of hundreds of hours of dyno and street testing. Mail order tunes are for mostly bolt-ons cars including nitrous and small cams or for more serious setups with larger injectors are typically used to get the vehicle into good enough shape to be able to drive it around and get it broken in for dyno or WOT tuning. Mail order tunes are not a substitute for dyno tuning with radical setups. If you are bringing the car back to us for dyno tuning, you may deduct 80% of the mail order tune price from the cost of a full tune!
