you can take it out.. no problem with that..if it doesn't suits you, then return it to me..btw, i'll give you the chip before the day you are going to solder it into ur ecu without taking ur payment. I'll give you a 3 days installation( if 3 days is not enough then tell me how many days you need).. and if you paid, i'll make sure i give the money back to you..thanks!!
