Hi David,
Around the $500-700 mark would be for any piggyback computer mate, either the Standback or Haltech. For min of 2 cars i can definitely do $500 flat, no problem.
Flash tune i could arrange for $600per flash tune, minimum 3 cars, which would include the days dyno time for the first car, 3 hours for the second. Another option i could provide would be say $250 for a flash on top of a piggyback tune, this would redo the throttle and desired torque map, remove all limiters, redo camshaft position maps - basically everything but the ignition and fuel side of things.
Hope that sounds reasonable.
Thanks,
Cihan
PS> i will be doing automotive related work & tuning on Friday evening + Saturdays only come next week. That may suit some of you that find it hard getting time off
