I have a frpp pro-cal tuner and k&n panel filter that came with the tuner for computer code ZXDO , this tuner will only work for this computer code , it will be the 4 digit code on your PCM under the hood . I have all paper work receipts and original box . I decided to void my warranty and went with a Lund tune. This will still keep your warranty if you take it to the dealership to be installed. Paid $379 plus shipping will sell for $208 shipped . Price is firm .
