Hello there DSMers,..
Well we have this 92 awd eclpise, with nothing but a MBC, boost guage and air/feul guage on it!!
It's set to run 15 psi, and the guage DOES read that too, but I'ts just that (exmple): in first gear, I release the clutch so that the car is rolling and then floor the throttlepedal, I hear this turbo"SSSSHHHHH" and read 15 psi on the guage, but the car feels really sluggish!!! then I hit second gear and its the same and then third gear and just after 3500 rpm orso it begins to pull real hard, LIKE IT SHOOT DO WITH 15PSI. Real strange, this only happens when I fully floor the throttle pedal, If I press it gently till like 4000rpm and then floor it, it goes right away!!!!!very fast, as it's expected to!!!!!
Why could this be happening???
This is my first dsm, but I'm very familiar with supercharged F-bodies, and what this DSM does is it feels as if the timing is being retarded very badly...
Could that be???? if so, what device(sensor or so) is doing that, (retarding the car when it's floored!!)
Any help woul be greatly appreciated!!

Thnx for replying!
But if it has a leak, how can I still read 15psi on the guage, and when I press the throttle pedal gently it does just fine!!...?? Thast should mean there is no leak right???
 
yes the same thing happened to me, very large boost leak (for the spool and no power.

the pedal lightly down and seeing more power had to do with an overhacked mas on mine, swapped out the mas too and she runs great now.

id look into a falty mas, your car should pull at all really in any gear if it had a boost leak that bad

and if you have to get a new one go with the 3.5" GM mas and the translator, but gut some type of logger too so you dont blow the engine from running to lean

i have a used one from a police interceptor motor i can let go for 75
