Hey guys having some fuel related issue and can’t seem to narrow it down. The car right now has FIC 2150s and a walbro 450. I was having an issue every time the turbo would start to spool as soon as I hit 5k I just get back firing and breaking up and it’s lean. At first I thought it was maybe just the anti lag turned on and activating. I turned it off via link and the issue remained. I was pretty positive then that maybe just the pump wasn’t holding pressure under WOT. So I drilled out the stock feed and installed a bulkhead fitting and I was pretty sure that would fix it. Still again this issue remains.... it seems like fuel pressure just isn’t rising when I’m getting into boost. Could maybe the regulator be bad? It has an aftermarket Fuel lab regulator. I can’t think of what else it could be. The regulator is about 6 years old. There is no fuel in the vac line. Any help would be great! Thanks in advance.
