I have just bought my first mustang a 2000 GT with about 60000 miles on it and I am looking to get more horse power but I do not know wher to start. It currently has the FIPK system and that is it, it might have the chip but I do not know. What can I do to imporve the performance. I was also wanting to replace the shifter but I do not know what transmission I have in this year car. Thanks Alot--I look forward to the help
