If you didn't notice a difference in the superchip then good luck. That more than anyting you sould have noticed. You do know that with ANY mod you will not automatically be thrown back in your seat Fast and Furious style. That takes a lot of $$$$$$$$$$$$$$$$$...... Y-pipe and a full exaust you sould notice a difference. If you don't with that then you better just save about 6-G's for that turbo kit or sell your car. Sounds like you expect too much for too little mula.
