RE: High Altitude Turbo Bar Question

["Tim Miller" <tjmill1@uswest.com>]

I have a 92 S4 and live in Denver.   The dash computer reads .9 bar prior to
starting the car.   At idle the computer reads .5 bar.   The max I can get it
to is 2.3 bar.   My problem is that there is a power hesitation when I floor
the car.  Also the Check Engine light will come on at times when the
hesitation occurs.   The car has the TAP Chip and K&N filter.   I bought the
car in Chicago and drove it back.  I had full power at the lower altitude.  
Any suggestions?
