Actually, Dinan and GIAC were trouble free way back when. They just charged an arm and a leg, so most folks stuck with piggy backs, which the stock ecu, abused on the track. Dinan technically made the best tune even though they never did one for people with catless downpipes, cuz they wanted to stay CARB legal. Dinan's tune addressed deep seeded issues, such as the ecu being in economy mode, and thus insisting on oil temps of 245F+ for optimal combustion. Dinan, was able to increase water pump speed, for example, something that Cobb simply can't do, even today. What cobb did was give us the ability to flash the car, with free, and customizable maps, in a hand held flash tune, for <$700. Very nice, but you can't compare it to a full flash tune like Dinan's or Renntech.
