I just freshened up my engine with new rings and bearings. I also added PP 5.3 stage 2 heads, 230/237 Lunati Cam, LS6 intake. Its scheduled to go to Speed Inc on April 2nd. They want me to put some miles on the car before I take it to be dynoed so that i can somewhat deat the rings. Now to my question. The car will not idle at all, can I drill the throttle plate to help the idle now? Or will that be a no-no with the tuning going to be done in three weeks? If its a bad idea, I will just deal with two footing the car until it can be tuned. If its alright, ill go ahead and drill the TB plate to make the break in a little easier on me.

P.s. Sorry if this doesnt belong here, I was torn on whether to post it here or in the External engine.
Thanks in advance for the replies.

 

I drilled holes in mt T.B. to help it idle. I've since had it tuned and it still idles where I want it to. The IAC will compensate for the holes you drill in the T.B.

 

I would drill it slightly, not huge just a little, to help it idle.
