Starting modded car with stock chip

[72firebird]

Well I'm almost done putting my car back together but I just want to check and make sure everything works. I'm putting 42 lbs injectors, PT51, 3000 stall l/u, and had my transmission built by Janis Transmission. I just want to start the car and make sure everything is functioning correctly, I'm not going to try building boost or drive it around. However my chip was shipped out yesterday and is on it's way here. I was wondering if it was ok to start the car and let it run at idle and put the transmission in gear while on the jackstands was ok to do with the stock chip.

You'll foul the plugs putting a stock injector chip on 009's. One way to get around it sorta off. is drop your fuel pressure to like 32 PSI line off.. and lean it out.
