hey guys I posted my problem on here before, as I drive it a little more I am learning a little more about the issue, i notice it starts losing fuel pressure in 5th and 6th gear right at 1500-1600 rpm above and below that point it runs great. will go from 10k-15k psi to 2.2k psi real quick i don't know if that sparks anything for you guys thanks guys

i have REPLACED:
CP3/fuel regulator
added lift pump
race plug
fuel psi sensor
fuel lines
bypassed filter head
cleaned tank and pick up
throttle position sensor
tested multiple sesnors
put back to stock tunes
