Truck has taken longer to start last couple weeks, batterys were around 4 years old so decided to get 2 new Interstate's from Costco. Truck starts a little faster now but noticed my ICP pressure sensor is reading 580 at idle. Is this a problem? Using the Scangauge II.

 

580 hot idle is right on the money

 

580psi ICP/22% IPR is money for a later build.

 

I did not know this little nugget of information. Checked my numbers today and they are right there. Good to know. Always learning something here.
