Bernd,
I have been chasing this problem for months! I have a 5.2 with a Vortech. I
have spent more hours trying to reprogram the aux fuel computer to remove the
part throttle lean condition with only marginal results. I have three
questions for you, where did you buy the check valves, what are you using to
read the map output and are you going to let the blower manufactures in on
this? Thanks in advance.

<< I'll be drawing up a schematic later on tonight. But here's the how and
why:
How:
From the MAP port on the TB, install a 3-way vacuum "T" with a one-way check
valve before the "T" and a one-way check valve (reversed) on the side of the
"T". The other side of the "T" goes to the MAP sensor.
What happens is under normal vacuum (no boost) the MAP receives a normal
signal.
Under boost the reversed check valve will bleed off boost to the atmosphere
there by removing the 30.8" reading from the MAP when under boost.
Yes...30.8" of vacuum...we tested this on a '99 Supercharged R/T as well as
my
Supercharger V6....if you don't believe me, i'll send you the active
(recorded)
log files from the runs.
I've put together a temporary system but will re-vamp it tonight to better
fit
cosmetically.
