If what you have in mind is saving money then get an Ash or any other proven chip because they are all made from modified JWT code anyway. If you want to be sure you get what is best for our cars and the knowing that the code in the chip has not been tampered with in any way AND you would like to contribute to the original developer of the performance chip AND you want the best in safety backed by the best guarantee, go with JWT. Just don't fall for all the selling hype about JWT not having a safety map because thats BS. There is nothing wrong with the JWT code. It has all the necessary safety features that the original stock chip has including safety boost. Once you get a JWT chip and if you want to get the "POWER" your car is capable of delivering but you do not want to pay the cost of or learn how to use an engine managment system, find a good tuner, have them back up the original JWT code and then use the JWT chip as a starting point using an emulator and have them tune the car on a dyno. But, if all you want is reliable plug and play with safety and guarantee in mind then go with JWT. If you don't want to pay the cost for a new JWT system, check around for a used JWT chip and find an inexpensive yet experienced person to socket your ECU and install boost jets or an electronic boost controller.
