Thanks for the replies. They were very helpful.
So I started calling around, and realized this all has become a moot point. I do not have the Oil Cooler installed and thus, cannot install the PPK. I imagine if the car cannot get the PPK, then it probably cannot get the JB4 either.
Oh well, looks like the car has to remain stock
Though, I did find out... installing the additional oil cooler alone is $2000... plus the cost of the tune. Probably not worth it
