the new aa chip helped me hang a 01 lightning and a 98 cobra with 4.10 gearing their asses late last night with noone around. most fun i've had in my in a while - watching my friends in their muscle cars get steaming mad when my 3.0 was hanging and then slightly walk away. many times as well. all 3 of us had our w's and l's but for the most part i was the champ of the night. i know the m3 is made for the twisties but isn't it great how it is a stoplight stud as well. definitely gives the muscle mustangs and "fast" fords a nice surprise. my buddy in the 98 cobra i have beat in the 1st and 2nd gears but his 3rd is more powerful than mine so in a 1/4 mile he'd probably have a couple tenths on me . just thought i'd share my enthusiasm for the dual purpose car we all have (twisties and a decent dragster)
