I am buying Dakota Digital gauges. For the fuel pressure I have my choice of sending units. 0 to 75 or 0 to 150. The 0 to 75 is more accurate than the 0 to 150. I did a search on here seems like most people with my mods say the highest they see is high 60 to low 70. Will the 0 to 75 be good enough. Any one seeing over 75 besides the 10 to 12 sec guys?
My mods not updates to my sig are.
STS max 8 psi maybe 10 some day
Meth inject
Delphi 44 injectors
wabro in-line 255

 

You don't need over 75 psi. If you do go over consistantly it destroys the injectors. Makes them leak. The last time I saw 75 psi fuel was when I was still screwing around with an FMU trying to tune for boost. FMUs suck.
