I have read it is typically a good combo but each car is different.
I haven't tried it yet but plan to. Another side note is that Autos/Tip's don't seem to hit limp mode as much as manuals... Not sure why, prob because our torque isn't as sudden.
Let us know in detail how it turns out.
Check the MKIV classifieds for the J valve. Usually, selling for $50 bucks. I think the stock is a H valve. There are several, all with different letters, hence H and J. They look the same, but do different things. The ECS racing valve has a letter also, but I forgot what it is. Be careful though, the ECS threw a CEL in my friends 4speed auto. The J works best for my car and it performs well. It spikes up the boost, holds it, and releases it smoothly. Also check Impex(www.vwparts.com) in the specials listed on the first page. They have it on sale now!
I tried the n75 H, J, F with my mods
The stock f valve was defintely the worst. No spike and couldnt hold boost.
The J valve was the best for me... surging was less.
H valve had the highest boost spike but it was surging like crazy which made my car annoying and slow to drive.
