After having an intermittent throttle input issue that sidelined me from taking the car to Charlotte last weekend, which i thought was a faulty WB 02 sensor, just before we were going to load her up in the trailer yesterday, she starting developing the same problem again, and then proceded to take almost no throttle at all. We checked all of the TEC GT parameters, perfect tune. She was getting fire. The summit racing inline fuel pressure gauge read a good 60psi that only flucutated marginally with throttle. We were worried about $hit in the tank, so drained the tank and replaced the fuel and filter. Still acting like fuel delivery issues. Replaced injectors... still no dice. I arrived at the shop after work at 8pm last nite and maybe being of more fresh a mind than my shop guy (who had been working frantically all day on her, as he was also trailering her to palm beach) i decided to hook up a standard diagnostic fuel gauge to the Carrera rail access nippple.... fuel pressure was dramatically dropping with throttle input.. #$%^& POS Summit racing inline gauge had been inaccurate and we had been chasing our tails all day when Fuel pressure issues were the culprit all along. The pump is a Bosch 44 which is only about a year old!!!!!!!!!... need some input from you guys about bullet-proof fuel delivery, see new thread.

So at 10pm last nite, with no possibility of getting a new pump in time to make it down there, we threw in the towel on getting her down there this weekend

Good news is, i am still coming, but won't be there for the track nite, as my early private flight got cancelled due to mechanical issues on the plane (imagine that) but i had a back-up commercial flight that gets in at 11:30pm tonight.

It is what it is.

Have fun at the track tonight guys, i'll c u sat morning. Looking forward to meeting all u guys.
