I just installed my electric fuel pressure gauge...

Im reading 50 psi at idle w/regulator connected, 58 psi at idle w/ regulator disconnected, and 56-57 at WOT at the 1-2 and 3-4 shifts.

My whipple instructions say that i need a minum of 61 psi +/- 2 psi at idle, and no lower than 59 psi at WOT (although it says the factory allowed range is 55-62 psi).

It says to get a new gauge if it is not correct, or take in to get fixed, but it is a brand new autometer gauge.

Any ideas?? Please?? I am hoping to install this thing tomorrow. The only thing not jiving with the instructions is that I have 1/4 tank of fuel, and they want 1/8 tank. Will the extra 1/8 tank really make a difference?

03 5.3 Silverado, 37,000 miles, new fuel filter at 29,000 miles.

Thanks, Bob

 

those numbers sound fine to me. slap that bitch on there.

the time to really keep an eye on the gauge is after you get the boost and at the top of each gear. you will clearly see the needle dip right before the shift once the pump is maxed out.

 

LOL! OK then, I will! BTW, I watched your vid the other night. BITCHIN!!!

Thanks for the reply! Bob

 

i never see over 62 psi at wide open throttle with my whipple

 

Well, I finished the install this morning around 10:30. WOW, she runs great!! PSI is about 60-61 at WOT.

 

sounds about right to me.

 

I love my whipple. Did you install the controller, or opt for programming?

 

i have all the whipple craptronics but have a set of 44lb injectors wating for install and would like to have it tuned to get rid of all the whipple stuff

 

You won't be sorry when you do!

 

where did you get your 6.0 how much was it?
how much was the nelson tune?
