Default Cadillac XLR N* PCM

I saw an XLR the other day and it had a N* badge on the rear. Didn't know they came with them. Are they rated the same 300hp as a Deville. If not, has anyone tried to use PCM in a GXP with any success?

they are the RWD version, the non-supercharged were something like 320HP.

but there is no reason to swap the PCM, and in fact it may cause a LOT of problems.

the major difference between the 275 and 300HP NorthStars were the cams, not the tuning.

So a cam swap is possible?

Unless someone has cracked the GXP PCM you wouldn't be able to make any tuning changes so while it might be possible to swap the cams you won't be able to make any changes to the PCM
