Map sensor sees Boost
 
When I begin to boost the car goes in limp mode....the map sensor sees the boost.
I'm using 450cc injectors and a map hack.
The car runs and idles nicely when not in boost, but as soon as boosts it goes into limp mode. What could it be?

you most likey are running too rich and need to cut back the voltage to the map sensor some more. i had the same problem when i would hit 7-10psi in third and forth gear, then i leaned out the afc some to cut back the voltage some more and now it hits almost perfect ;D try leaning out your settings...

I got the problem
My A6 thorttle body has a nipple that goes to the map sensor....and it looked kinda weird...I T'd the map sensor to another vacume soarce (the one that goes to the dashpot)...well ;D I boosted finally.
I think the nipple on the thorttle body closes or something when going into boost
