gauge says 9psi dsmlink says 20psi??

[Gary 420A RS]

anyone know why? i took the gauge back off and redid all the connections and it still reads the same. no matter how i adjust the boost controller it stays at 9psi. and idles at -19?? have no idea why. dsm link is logging above this and going through a full spectrum to 20psi. anyone know why or had this before..

try a new guage, sounds broke.

check your airflow settings, also check for boost leaks.

ill check all the pipes and everything tomorrow. sounds funny how it still wont past 9psi. and never once spikes higher.. and with dsm link everything runs fine and you would have no idea.. it might be the gauge..?? who knows.. ill check it over tomorrow.

Unless you are using a the GM sensor, DSMLink outputs a boost estimate based on your airflow. If you are using MAFT, have boost leaks, or anything else that throws off your actual airflow readings, the boost estimate will be off.

i have selected on dsm link to use a fake maft. even though i have the stock 2g maft hooked up.. ill have to check on that. it might as well be the problem. i sure hope so.. cause i checked and theres no boost leaks.

Why?

i just remember messing around with it so ill have to go in there and make sure i fix it and hopefuly that is the problem.

Don't touch things unless you know what they are. Read the manual

well i set it back and i checked all the lines again. nothing changed. it still reads wrong. i also think one of my exhaust gaskets are done for. its sputters around 4.5k almost like the maf sensor is off. you know that feeling when you press the gas and you know you have more but its not there?
