Look at it 1to1
Most tt chips want to be 43psi.
And the e85 cars want higher pressures like 50 or more.
So 43 and 30psi your looking at 73psi and if your an e85 car that wants to run 30psi your 80psi.
Even if pumps were falling off I would see mid 60s
It's when it needed more pressure you found out,sometimes the hard way.
As you have alky and your base pressure is low and your only running 25psi you may not see an issue.
It's what the motor needs to satisfy
Just jeep the alky flowing
Sounds like you are fine for now
Keep looking at pressure.
I've had them cut out a bit and then literally fail and I was stuck on the side of the road till pickup,
Your not really leaning on it at 25psi and alky,so you may get more time than most.
