Map Sensor

[IROCNParts]

so I think I figured out why my car is running so "great"
I datalogged my last track run and noticed the following
the map sensor is reading @ like 55% at full throttle when it should be reading 90+
thus im getting only 50% of the fuel I should be getting
im now caught wondering if its because the line feeding it isnt thick enough or if the map sensor is fucked.

I whould think you whould have a spare one around to test :)

I assume that you've tried the obvious, like filters and other restrictions. If everything is okay, what is your o2 sensor reading? If it's reading rich then you should be okay. If its running lean, then ya you have problems. But with motor like that, you would notice I would imagine. What size fuel injectors, how much fuel rail pressure, and more importantly, how many gal/hr is your fuel pump(s)? Are you still running stock fuel lines? Seems like you could have a quite encompassing problem

With 8.5:1 compression and no power adder, I'd say the fuel system is fine for now. Just swap out that Map sensor that Dave sold you.

I tell you he fixed it to work like that, LOL
