Trying to get some questions answered for a friend of with 94 auto. We are trying to figure out the boost curve of this turbo and its capabilities. The turbo doesnt get spooled up till right at 5000 rpm's. When the boost comes in, its all at one time, you hardly feel any low are mid boost coming up, almost like he hit the N2O button. Basically I am just wondering if these are the natural characteristics of this turbo or is something not going right else where in the car. He has every bolt on but no bottom end work. He's running a Profec B boost controller, HKS AFR, stock ECU and injectors. Thanks in advance for the help.
