sts turbo problems
 

I have an sts turbo on my dodge ram hemi. but as soon as i get on it about 5 times the truck gets hotter and the turbo seems to sound louder, i have a 7 pound spring in it but sometimes it will go up to 9 pounds and the engine starts misfireing badly. does anyone have any suggestions ....:confused:

There may be blown seals on a turbo and kindly check wheather oil is coming out from exhaust.

May be vacuum line which is going through the turbo actuator is not connected well, or might be problem in the Turbo actuator, kindly check the same and if any problem persist then replace the same.
