Just bought a 2000 Mustang convertible. My mechanic, an old hot-rodder, told me that after I installed a K&N high flow air filter, he would be able to "tweak" the computer for better performance. He also said it would "easier to do" because I've got the 5-speed manual transmission.
I'm not mechanic -- can anyone explain what he's talking about? Is it harder to "spoof" the computer if you have an automatic transmission? If so, why?
Also, are there any other performance tweaks that can be done to the V-6 engine? (I just installed the K&N air filter.)
Thanks!
