Just installed Fuel Pressure Gauge. Kinda off?

I recently finally got my EGT adn Fuel Pressue gauges installed. The EGT seems to be working properly. But the Fuel pressure seems kinda high at idle. It hover's like at 38-40 at idle. When I first had it installed it was 34 @ idle.. Any ideas? Did the calibration on the unit go off? or is it just me? It's a Autometer Cobalt Series.

Get the A'PEXi pressure gauge to match your other ones.

thx...but it is in metric unit. I am lookin at the greddy one..140 for electronic, 52mm. seems a good deal. fits my gauge pod too.


have you scheduled a tunning session with ATP yet?




aimming 380whp?

But it won't match.

Haven't scheduled a dyno session yet... I'd be happy with 302 whp for now. Going to slowly work up to that number. :-)

perhaps a fuel line is pinched somewhere along the routing to the gauge...that can bind at that point and alter the reading.

with that air fed snail you would like to see that low number? you know you going to get quite a bit more then that, also your torque should be pretty high as well. I am predicting at least 340HP/355Lbs of torque

Trying not to keep my hopes up... a low dyno would motivate me to work harder.
