Yeah I have noticed similar pressure drops as the tank gets lower. And then if it's hot out - it contributes to the lower pressure. When I get over a 1/2 tank in 72 psi start up - then 65 -67 at idle. But last night as I was getting lower in fuel - and it was hot - stoplights were at 55 or so. If I get into the gas it always drops another 10 psi - don't know if this is normal.
Would have been a perfect night if you show'd at Hawrelak last night - would have been all the boosted Z's.
My z has doesn't want to start lately, I have do just tap the gas lightly - wondering if it's fuel pressure issue?
