The factory boost gauge is finnicky at best. They are all different, even on the same model car. My suggestion is to install an after market one that gives you true readings.

jrl.. where did you get the chip ? i had a mazda mx6 turbo and all you had to do was remove the ecu and solder in the new chip. it made a heck of a difference on the car.<p>is it the same on our volvo's ?

Ask on Volvospeed who their ECU flavor of the month is. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <br>The ECU I swapped was one out of an old R I bought and sold, it was a PEC unit, they don't make them anymore but it seems to be as good as others I've had. Installed a regular boost gauge last week, twisted the wastegate a couple of turns and in this heat it's running a steady 16 lbs, good early on boost with spikes to 18 or so.<br>Should be good for another pound or two in colder weather <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: (steve s)

wait. u have a 94 turbo?<p>if that's the case, then the above pic is useless for u.<p>u need the reverse intercooler piping, but u get the idea. those rubber pipes tend to go after 10 yrs <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">
