Ok, I have a 1990 dodge spirit with the 2.5 in it and i have a t4 50 trim turbo, FMIC, and Stage 3 cal, that used to throw down almost 25 to 30 pounds with the waste gate can unplugged. I have just recently rebuilt the motor have good compression all around, resealed the exhaust and checked for vacuum leaks and to make sure the G-valve was working properly. No leaks in the FMIC piping or the cooler itself, checked it all. Still nothing... the car will boost up to around 10 to 13 pounds with me pushing it hard and it gets there slowly on top of it. Also replaced the waste gate actuator with a 7psi big can. :bang head This has been an on going issue for about 2 weeks now with no success any input or advice would be appreciated. My preferred psi would be around 15 pounds or more in the near future and my boost times to be lower.
