More Problems!!!
More Problems!!! Well I got rid of the Typhoon intake and put on a ls6 intake. There were no sealing issues but just to be sure I did that for good measures. I also traded My 2 bar map for a 3 bar map. This is where the problem comes in.
And Yes it has a 3 bar tune on it for those that will ask!
I thought I traded with a pretty respectable FI guy here and until I talk to him I will Not mention any names. Car will not run at all with the 3 bar sensor plugged in. It starts for half a second and dies. No chance of it even running. So I turned up the fuel pressure to see if that helped nope. Got t up to 75 and nothing new.
Then I decided to plug in the 1 bar map to see if it would start. Much to my amazement the car started the first time. DId not run well by any means, so I turned down the fuel pressure the more I turned it down the better it ran was down to 9psi before it ran ok.
So in summary, map I got was bad now I do not even have a 2 bar map. I just want to try and finish this thing. Everyone that says that these projects will nickle and dime you..... Pfff they are not exaggerating.
So does anyone have a working 3 bar that they want to get rid of.

I had the same problem lately. I switched from a 1 bar to a 3 bar and the car did the same exact thing...ran for a second and then died. Would not run at all. I switched back and it works fine. I then hooked up my scantool and watched the map voltage with the 1 bar and it was fluctuating in the 2.5 range. I then redid the wiring a second time and tried the 3 bar again and the car only read around .5 range. I then switched back again and never tried it again because I was pissed. I am anxious to see if you actually got a bad sensor or if something else may be wrong. I still get a p0106 code pretty often, but once I clear it the car runs fine again. I haven't tried testing the voltages from the ground or reference wires. Good luck.

Same deal when going from a 2 to 3 bar. Thanks very much, and I apologize I probably should have mentioned that. Speed inc did put a 3 bar tune on it already, I had a 2 bar map on it and it was not running well obviously.
I am going to check some values tomorrow with autotap and see if I can come up with anything but as of right now I have been told that this sensor absolutely worked. So tomorrow we will see what happens

It was my 3 bar sensor and adapter harness 
Tomorrow we will get some readings and if my sensor is bad I will send his back. The fact that his car runs with the 1bar makes me wonder about the 3bar tune. Hopefully we will get you going ASAP!!!!

Verdad Gallardo It only runs if I put the fuel pressure down to 9psi. This is very similar to what I had to do with the 2 bar map in it. except it was at 28psi with the 2 bar in it.
Question would be why would giving less fuel make it run. I was having a conversation with cablebandit and he made a very valid point to me. Why would less fuel make it run better, as you change sensors and go up (1 bar to 2 bar and then to 3 bar) should you not have to add fuel or is this not correct!

that is hilarious, We are both on the same page now at least. So do you have any explanation on what might be going on with my car now and that the 3bar is not working.... You know what never mind, let me wait and see what the sensors say tomorrow.
yup I had a similar issue. The sensor that I had to get was a universal it I guess. What way I thought was right was not. So I had to flip the sensor around. Oh my god started and ran a ton better. I feel bad because me and Cable spent probably 60 dollars in shipping because of the damn sensors

it wasnt the pinout being wrong...just that the plug would slide on EITHER way....and it LOOKS like the way it should go is right but it is wrong...it flips over the other way
Mine would fit the other way too once I took off the little plastic retaining clip that snaps on, I pulled the pins out and reversed them because the notch on the other side was bigger and couldnt unplug if somethint pulled on the wires.
