Greetings -
I recently installed a GFB DV+ and Velossa Big Mouth. While at it, I tightened all the clamps on the Depo IC and hard pipes. I buttoned it all up, and the car was driving great, consistently hitting 26.5lbs boost on my Dizzy E30 tune. I filled up the car a few days later, and went for a spirited drive, only to find I would only hit about 23.5lbs, and on top of that, the boost would then taper off to redline, dropping as low as 12lbs. I've gotten back under the car and ensured all pipes are connected snugly and all clamps are tight.
I cannot figure out what has happened... could the DV+ not be holding the seal properly?
Supporting mods include Cobb intake, Whoosh Symposer delete, Thermal Exhaust and step colder plugs with less than 5k mi on them.
Any ideas?
