Heres my issue:
When the fuel tank is below lets say 1/2 tank (gague is broken so i'm just guestimating) I get a condition where it feels like a large buck (hitting a brick wall) happens when accelerating quickly. When the tank is full or near full, this bucking does not occur. I have read up on fuel cut/boost leaks, and cannot find anything that relates to fuel tank level. I have replaced the fuel filter and fuel sock, and my fuel feed/return line is 6AN.
fuel - 6AN feed/return line, stock injectors, stock regulator, stock pump
Stock turbo
Injen style intake
Megan racing downpipe
Greddy (likely replica) exhaust from downpipe back
crushed 1g bov
stock ecu
hard intercooler pipes
I have recently done a clutch job and most of the IC piping had to come off for it. I clamped down the hoses as tight as I could get it, and inspected the hoses for any tears or cuts. The condition still occurs. I am basically ruling out boost leaks.
I accidentaly had my wastegate actuator not hooked up (fun, fast accident) to the line, and it boosted up to 20psi without an issue when I had a full tank.
Fuel pressure regulator? Fuel pump? Fuel gague safety something?
Please toss around some ideas, I really am stuck here and want to remedy this issue as it causes me to make too many trips to the gas station.
