My first boost graph (awwww)...
<center><img src="http://pictureposter.audiworld.com/79676/020505_boost_graph.jpg"></center><p>Hey guys, this is my first boost graph I put together. I just got my VAG last week and finally got a chance to play with it this past weekend. I'm pretty sure I did this right, recorded blocks 115 and 116, then I transposed the data to excel. The runs were not WOT but close to it in 1st and 2nd gears, 2 runs consecutively (completely stock).
As far as these graphs go, would these give you your best diagnosis as to whether or not you have a boost leak? I don't know what they should or shouldn't look like and what to look for as far as boost leak. Do you guys mind checking this out and see if I did this right or not? I may have done this completely wrong for all I know. I'm still semi-noob so I'll take any criticism you have (good or bad).

What is block 116? I've never seen that logged by anyone before.
I suggest you log block 115 alone at wide open throttle (WOT). You can either do a single gear (3rd preferred) or you can do 1st-2nd-3rd log. Here is a few examples of boost logs:
3 Gears:

1 Gear:

Actual and requested boost should follow each other relatively closely unless there are outside variables affecting boost, such as a manual boost controller (MBC). All 3 of these logs above have a MBC involved, which explains the actual and requested not following eachother exactly.
