boost problem

[Oliver M. Llenado]

here is the story,

1.1 bar, replaced the mm hose 
1.2 bar, then discovered a leak in the upper & lower wastegate hose, replaced it then 
1.0 bar,

there is a writeup in sjm's site on trouble shooting the wire connection, usually just removing and re-installing the thing solves the problem.

your on the right track, I just disconnected the muti func temp switch pin & clean it with an electronic parts cleaner and re-installed it, now am getting 1.4 bar,
sometimes the temp gauge fails to work, I just re-insert the pin connection.

the temp sensor is located near the radiator hose, it is covered with a rubber cap, 4 wire pin. mine is installed upside down.

does your temp gauge work?, 

with regards to the wastegate diap, you can test the diap with a vacuum, sjm also have some write-ups although I did not go that far.

I will be installing an autometer boost gate which I got from eBay and a pair of Infinity tweeters I love working on this car.

gud luck on your repairs.

  Oliver:  Did you ever get this problem resolved.  I am having a similar problem with my 5kcsq ... I have a new MM hose, a new breather hose, replaced all injector seals and injectors and after all of this the best I am able to get in boost is 1 bar except when I floor the accelerator and the engine takes a long time to get to 1.3 bar.  The car is very sluggish, and all the work seems to have made no difference at all in terms of performance.  All I am looking for is to get to stock performance.  

  I also have a 90 200 TQW which does not handle as well as the 87 5kcsq sedan but has a significantly more responsive engine.

  Any suggestions will be appreciated.

    after discovering that the lower wastegate hose is limp and leaking, I replaced it .   
    was experiencing 1.2 bar boost with the leaking hose, when I replaced the hose just 1.0 bar.

    already replaced the michelin man hose, throttle switch, upper wastegate solenoid hose, correct plugs, new wires, 
    the temp gauge doesnt get high though I was thinking the multi temp sensor needs replacing, I just replace all the possible parts that needs replacing.
    any suggestions?, next step is the temp sensor, where can i find this? then the wastegate diap'
