so i am lookin into manual boost controllers for my 2003 MSP just bc they are less expensive then the digital ones. My whole motor is stock nothing has been done to it and now im looking for more boost. A friend with the same MSP said that my motor could handle 10 PSI no probblem on stock internals and around 12 PSI ill get fuel cut? On stock internals Whats the most my car should be able to handle im still a little nervous just to put the boost controller in and turn it up.
