If i slap a BA2400 on my termee.. will I need to scale down the PCM?

At first i was going to slap it in and put in a generic 2400 Xfer function.. but then I read somewhere that the PCM is limited to the amount of air it can calculate.. and so you'd need to scale down the right tables parameters etc.. to make it work..

Burntire you tuned your own car right? you must have been at this stage once??
