    5.3 Turbo warm start problems Help Please

    Thanks in advanced for the help, put a 76mm turbo on 5.3, 80# deka injectors, Plugs, all new sensors on a 35k truck, wideband, boost/vacuum PLX
    sheet metal intake.
    I had the truck mail order tuned until the cam swap and dyno tune next year. On a budget.
    The truck runs great only problem they left me hanging with the idle. I played with retarding the Idle spark table. cold start under 50 deg. F, starts on first bump. once driven awhile restarting is a problem it cranks for 4-6 seconds then starts to fire goes to 700 rpm then chokes down and stalls. recrank and it will fireup abit better then it will get going as normal and holding a nice idle.
    put it in gear and drives like a engine on steroids. why the warm start up problem.

    appreciate any help.
