Read a bit.

J is stock on the 1.8t's with K03s.

H is the "race valve" that peaks a bit more your boost at low rpm.

"the ECS RACE N75 slows the speed at which the wastegate reacts to ECU boost control signals. The result is a smoother boost curve. Many customers who had "jerky" power curves found that not only has the RACE N75 valve added extra horsepower, but has nearly eliminated any irregularities in their engines power curve."
 
J is not stock, it spikes approx 1-2psi less then the H (it's also oriented backwards like the H), some say it's boosts smoother than the H valve.
