Roughedgez here are your Boost plots... [edited]
First of all. WHOLY SHEEEEET!!! Does your car pull!! Boy was I was planted in my seat. <g> Now I have to try race gas! You said Paterson and Ledgewood? Where in Paterson?
I was very surprised the boost was relatively low. I guess as you said in XR chip it's mostly timing. [NOT! I goofed on the conversion formula. Pics below are revised]
People please chime in and analyze. The car has <a href="https://forums.audiworld.com/s4/msgs/1021896.phtml">ghl downpipes and exhaust</a>
The first two look good to me. The last two are a little strange with actual boost jumping slightly above requested. I don't remember what gear those were in.

Did you get detonation from misfire codes or boost curves?
I didn't have time to run any other blocks but he'll probably be back this week.
Looked at the <a href="http://www.ross-tech.com/vag-com/m_blocks/">meas. block reference</a>
and was going to log 2 and 3
2 - RPM, Load, Mean injection time, Air mass and
3 - RPM, Air mass, Throttle valve angle (Potentiometer), Ignition angle (actual)
Anything else? 010 - 019? or 020-029?

What units is the boost in? how did you convert? That doesn't seem right for any 1bar chip
if I assume it's measured in relative PSI. I can't say I've definately ever seen a GIAC XR boost graph before, but I have to assume it's higher than 12 PSI. What was the peak mbar reading that was actually recorded?
