2.6 Gen1 with Starion engine/turbo/TBI conversion and Megasquirt running 6AN fuel feed from Walbro 255lph pump. I've driven around 3000 miles now and it's been PERFECT other than a couple of occasions where I noticed it was studdering when the clutch was pushed in and braking. Took me a while to figure out the common denominator. It only happens 1/4 tank or less (still a good 3-4 gallons left based on fill-ups) and I brake hard when turning right. I'm actually around 1/8 right now and can make it do it consistently. But only braking aggressively while turning right (like into my driveway). Can actually hear the pump lose suction for a split second with the windows up/radio off/etc.

I can't tell squat from my manuals about how the pickup sits in there. Any recommendations or is the 255 pump and large fuel lines just pulling too much fuel for a tank/pickup designed for a little carb? Don't want to pull tank till I have a good plan. Any advice would be appreciated.
