skirkland1980 Posted December 3, 2012 Share Posted December 3, 2012 I went to twiggs today and drag raced the z. By the way I highly recommend twiggs on sunday. The car ran great with one exception, the car ran so rich at 6000 rpm at 15 psi, like at shift rpm, that the car would bog down. I logged in to tunerstudio and tried to lower the fuel but had the same results. I''ve read a lot about this problem but no fixes. PLEase HELP .

skirkland1980 Posted December 7, 2012 Author Share Posted December 7, 2012 Well I went hoping to get some E.Ts but I found out that they call it street nites because it's 'arm drop' with no tree, no timing. It was really fun though. We raced from the end of the track where there was no rubber. I enjoyed eating V8 cars that couldn't get traction.

skirkland1980 Posted December 9, 2012 Author Share Posted December 9, 2012 Went back today. I discovered that it's caused by two problems. One was the rev limiter was set at 6000 so I bumped it to 6800. The second problem is the transmission is very hesitant to shift into third. Back to the drawing board...

skirkland1980 Posted January 14, 2013 Author Share Posted January 14, 2013 I have an update. For the sloppy 2-3 shift I installed a transgo shift kit part number 700-2-3 and a .500" boost valve. The kit did not recommend the .500" boost valve but that was all that was available and it works great. Quote Link to comment Share on other sites More sharing options...
