Qsx15 turbo wastegate control valve?

first of all, you need the get that engine killing garbage can tuning box off that engine!. Also that CM570 only needs about 36 psi boost MAX! to make full power, and anything more will cause its premature demise!.

NEXT, it needs to be set back 100% factory spec and then put the program in it that belongs in it according to the vehicle specs and ser# for the engine... and stop lolly-gagging it to back-woods redneck death!.


After that, you need to put it on an actual dyno to get a proper base-line and see if the power output actually matches the programming, instead of guessing and d$icking around with 'how you feel' its doing instead of actually seeing what it is doing properly!.

- and if it is being help back.. STOP GUESSING !!!! AND MONITOR THE 'CBL_Fueling_State' / 'FSFNFLST' (what circuit is controlling the fueling), what engine operating mode its running in, and the other important settings that will tell you exactly what its doing (in cal$term) and then someone can tell EXACTLY why it might not be giving it full power/torque, etc. instead of assuming all the time like a blind-man that its your turbo.
similar to this: (cm870 example shown in this post)... ref: http://rawze.com/forums/uploads/202009/p...c4ca40.png

I.E.> ACTUALLY TROUBLESHOOT IT INSTEAD OF GUESSING!!!
