Wooooo Hooooo

Spent a few hours at Tony Wildman's place today.

He hooked up the diagnostic PC to do a few tests, but the PCM kept
on faulting.... not a good sign... Took it for a ride to show the
symptom. Was able to reproduce...

Went back to Tony's and he installed a full blown crazy chip in it just
to see what would happen. Could get to 13lbs of boost then back to
zero boost and a ton of black smoke (that was kinda cool). So he
disconnected the wastegate tube, same issue. Hmmmmm....

Next he disconnected the intake to eliminate the complete intake
system.... ZOOOMM!! 25lbs of boost!!

Turned out to be an intake restriction that is now resolved!!! Still
may have a PCM issue, but doesnt seem to impact the running
of the truck.

Cant thank Tony enough! Gonna get me a chip when the budget
will allow in a few months..
