what he said. Not only is it NOT a good idea to run it hard untuned (timing, and all sorts of **** are out of whack) but putting bigger injectors in it only fueled the fire (terrible pun). Put the stocks back in it until you get it to the tuner. and you WILL need them.

there have been only slight pulls nothing WOT.... and i only went to 30's just because i had them lying around. 24 to 30 isnt such a huge increase. just a little something extra. i was "hoping for it to maybe idle. i knew my odds and thought maybe i would get lucky." its a really good tuner so it will be spot on. just wondering exactly how well he actually will get it to idle....

At the very least, it's gonna sound mean as hell.

run your stock injectors man

clutch and brake[put it in neutral to brake] with your left and keep it running with your right

it will idle when it is tuned
