I just installed a new JLT CAI and X3. Here's the deal. Flash went fine as far as I can tell.#1 It wont idle consistantly. #2 It backfires/pop's after I accelerate. #3 1st gear accelleration is great, when I shift to 2nd gear, it falls on it's face then starts to accellerate, 3rd gear, same deal.#4 It knocks badly. Any ideas? I installed the canned tune for 87 octane.
