    silverado closes throttle and dies

    Greetings

    i am helping to tune a 2008 silverado. on WOT it closes throtle and dies, then it would not start until you erase all codes.

    what kind of intake are you using? are you spraying any nitrous?

    *Edit* looks like a forced inducted motor... what colour are the blades on the throttle bodies you are using.. I've had the same problems on some Magnacharged trucks.. at WOT it would just go into REP coz the motor wasn't strong enough to hold the throttle body steady.

    Spoke with Joe@leftcoast and he informed me they were R&Ding a new nick williams TB for the trucks that would work properly. Try getting in touch, or try the copper coloured Throttle bodies.

    I got the aluminum TB.. I use a Holley Hi RAM at 24 psi, no nitrous.

    We have used a cooper one ( stock for the truck) and it keeps doing the same

    thanks
