I see many here say you have to have the Power Commander along with the exhaust replacement to get the best performance. I have also read that some have just installed the PCV- AT with stock exhaust and are happy with the change in fuel that reduces the exhaust temp issue. How many of you have the dual channel AT compared to the single channel version? After taking the plastics off I think it is going to be pretty hard to fit the sensors on the headers but i could be wrong as i did not see dimensions of the sensors and weld bungs together. Any thoughts would be appriciated.
