CLS63 Boost problem
Hi all. New here. So i am having am issue with my CLS63.
i picked it up recently p30 pqckage. Bone stock. It made 475whp on conservativr dyno dynamics. Boost would peak at 11-12 and tapper off to 8psi. The performsnce was there. Ran 100-200kmh in 8.1-8.2 consistsntly.
then we loaded a tune. Peak boost went up to 20psi but would tapper off to about 12psi. The performance gain was big. Dropped 100-200 to 7.1 with a lot of spin and a passenger. At 2% incline.
the car did 7-8 strong pulls the boost just disapeared it starts of at 18psi and then drops to 3psi til the end of 4th- 5th gear.
star shows absolutely no codes. I ve chs ged the solenoid and vacuum pump. Made zero dofference. I ve also smoke tested the system found no leaks. I ve flashed the ecu back to stock file.made no difference. At this point i dont know what else to do.
any help will be hugely appreciated.
