Since I bought my car new off the lot I didn't want to go with JB4 - it would also help with the lag but could potentially void my warranty if it was ever discovered.
For the people wanting to street/drag race the PPK is certainly not the right tune, but for the daily drivers that want a more predictable and enjoyable experience I think the PPK delivers, albeit very subtle as the OP is finding out.
I completely agree with you. I bought mine used with only 7k miles so I thought I should try out the PPK first. And having researched reviews by some of the early adopters it seemed to have provided them exactly the kind of improvements I was looking for.
I guess I didn't have a better understanding of tuning in general and the biggest problem is I'm already getting greedy. I want more power!!!
