im using this one like i said nth special (

the reason i brought up weight is cause with my last one i had it set to 10lbs n never went over that. but once i had 3 other ppl with me (not small or skinny by any means) and i hit boost trying to get on the freeway at that point i hit close to 13lbs and my fuel cut off kicked in.
my pressure gauge was given to me by someone i think some off brand. but i have checked it wit a snap-on pressure/vacuum gauge and it reads correct every time n i check it monthly at that.
the way its set up i have the controller inside the car mounted by the e brake wit the line running to the engine bay through a small hole n the firewall by the horn across the firewall above the engine, and down by the turbo. one like goes to the waist gate actuator and the other goes to the turbo
