Not worth the plastic it's made from
"I bought this as a mild power boost to keep the factory transmission in one piece. Any time I try and change settings it ends up in “recovery mode� and this takes about 3-5 minutes each cycle. Best I've had is 3 cycles just to get it so I can adjust the tune. Then it's another 3-5 minutes of hoping it actually uploads and doesn't go back into “recovery mode� and start the process all over again. This thing is so bad it's the first time I've been bothered enough to write a review and I've had this for 6 months hoping it would “get better�. Wouldn't even make a good paperweight because of how flimsy it is"
