Turbo Boost Adjustment
If a boost gauge is to be installed do so at this time. Mount the gauge to the dash and carefully
route tube from gauge to turbo. (Drill small hole in dash and feed tube from gauge into dash,
behind instrument panel, down underneath with wire harness and up to turbo attaching tube
carefully with wire ties to harness). Remove boost line from Turbo and replace with 3/16" fuel line
and hose clamps. Install tee in new boost line and attach tube from gauge.
*
*If boost gauge is not permanently installed, install temporary gauge into boost line.
Loosen lock nut on turbo. Start vehicle & warm up long enough for the temp gauge to rise slightly.
To increase boost adjustment knob so the rod is shortened. At idle, increase boost until the turbo
whistles (it may be necessary to bump the throttle from time to time).
Adjust until 5-7 PSI of boost is achieved under load such as driving uphill. Tighten lock nut on
turbo (if temporary gauge is used, remove and install 3/16" fuel line with hose clamps to turbo as
the boost line).
* It may be necessary to readjust boost at a later time due to the controller bracket movement. If a
loss of power is noticed, readjust boost using the above instructions.
