HELP PLEASE - Fuel pressure problem. Guys we just started to boost about 36 psi on ethanol. 4,1 built engine & ETS PRO 1700. 100-200 3 sec. Everything looks good except one think. During hard acceleration on 2nd gear with big G force fuel pressure drops. On higher gears pressure looks OK so fuel pumps and fuel lines are OK. It looks like empty tank case but tank is full. Any ideas?

In one of his 8 other threads on the same issue he posted it wasnt even a fuel pressure issue. Some torque cap in the trans flash.
