Header Question

Is it recommended to get your chip re-tuned after putting a set of headers on?

JMS setup my chip and when I added the JBA's I called and asked CJ the same question. I told me no. BUT, I had a touch of fuel added anyway. Probably not needed but what the heck. I left the old tune in one of the programs just in case though.

I didn't think I would have to since it doesn't effect the amount of air coming into the engine. Just wanted to double check.

Thanks

I have read that it can affect the amount of air coming in. A faster spent charge exiting the exhaust port and "suck" in more intake air during overlap. I've also read that timing can be affected as well for basically the same reason. You actually get a cleaner charge with less left over gases from the previous spent fuel/air charge.

But with shorties these are rarely a problem... again so I've read.
