well keeping below 1100 is good that helps not roast the turbo. you need to also get Insite - about 250-350 on ebay with a inline 6 adapter, and find a member here that can remote into a laptop with another program to check the tune or get such program yourself from another source other than here and download the program and send it to our wonderful experts.


but insite and inline 6 will help alot in watching how the turbo is acting, how fast its spinning incase some assclown turned off the overspeed protections and its roasting bearings. if 28lbs of boost is all shes got at full throttle thats quite a bit low also matters what your HP/Torq ratings are.

also make sure to do EGR tuneup the program you have is unknown and could still be using EGR differential pressure sensors, also bad IMAPs, and Exhaust back pressure sensors can make "technicians" fault a turbo do to a sensor that doesnt throw codes but feeds the system bad information.
