I have built a 355 with a CC306, 36lb injectors, !EGR, !AIR.

Will this motor run at all on a stock tune? I really don't want to have to ship the pcm out only to take it right to a Dyno shop, and I don't want to pay the dyno shop to do the initial break in, so will the stock tune be enough to get it to run till I can get it to the dyno shop?

Please please help!

Also it only has the Upstream O2 due to longtubes

Put the stock injectors back in and it will be driveable. May not idle very well, though.

Yeah, you'll flood the motor with larger injectors and no tune.

okay I guess I will have to ship my pcm out then. Who is the best PCMforless or who?
I dont have the stock injectors.

You can try and turn the fuel pressure way down, if you have an adjustable regulator.

PCMforless is a good one.
