Its 1999 with ard 1000 box i read that on quadzilla website that wouldn't have anything to do with the fuel pressure gauge not working ? 1 other thing i noticed it never did this with my comp box the smoke is grey coming out of the exhaust if i switch it back to my comp box its jet black smoke. Im tried stock tune on level 10, the street tune for 7x10 injectors from you

Has anybody had this problem my quadzilla adrenaline shows 5-6 boost psi at idle and when i plugged in the fuel pressure sensor it only reads 3psi all the time but my regular pillar gauges read jist fine so whats going on with the quadzilla adrenaline i just bought it everything else works fine on it
