alrighty guys, i gotta 2000 f250 and i bought a chip from tony around december and i put it on but then sent it back in january cuz he said there was a bad batch of chips that were made, but anyway i got it back in march and i use to have 4 tunes and now i have six and i dont know what they are. but one of the tunes, i guess the extreme, makes my truck shake and idle like it has a dam cam in it. the tune makes the truck wicked fast and throw alot of smoke, but the truck rattles and i dunno, it just scares me. i just wanted to know if anyone knew anything about this. o yea and also another question, does anyone know if there should be oil in your intercooler pipes that run into the turbo? i got like small puddles of it. please help me out. thanks guys!!
