Like someone said, culprit really isn't the kit, it's the shotty tune job. This is the main reason why I'm super picky with tuners.

My WRX specifically goes to a tuner shop who specializes with Subies and only Subies. Why my Z isn't boosted, no shop really specializes with VQ motors. Last thing I need is a money pit like the OP.
