As August comes to a close, we are offering a one-week-only special on our custom programming. Trifecta Performance is the only company to offer full custom programming on a convenient, and easy-to-use handheld programmer, which we send to you. No PCM swap, no disassembly required. Crank relearn is never an issue! When you're finished with the programmer, send it back using the prepaid return shipping label!
