I just put in my dss 306, gt40p heads comp cam 260.268 split dur. 512 lift with match springs. 70mm t.b. c&l Mass air w/24 lb tube and fms 24lb inj. trick flow street intake. I can not get it to idle worth S@#T. It will idle but it hunts around then stalls. I have 15lb of vaccum on the guage. Any ideas any one. New o2 sensors too.I did not touch the fuel pressure yet.

 

where is your T.P.S set at? what kind of tb do you have. how does it run otherwise?
