h/c and tune ??'s
i just put a tsp228r and prc 5.3 stage 2 heads on my car with a set of tsp long tubes. tsp says tune required for autos, is it ok to drive the car with a tune for a while? i know ill get codes for the rear o2 sensors i just want to make sure the car isnt gonna run super lean and fry something. i have 42# injectors, should i put them in or use the stock ones until i get a tune schedualed? i really want to drive the car this weekend but cant get on a dyno for at least a week. but im not gonna chance it if im gonna f something up.

Good questions!
I just did my H/C change with larger injectors. If your going to just putt around with the old injectors I would say "OK". Do not get into the throttle! You only need the bigger injectors when you really load the engine. Watch your engine temps. High heat is a sign of a lean condition. Avoid this at all costs. You can do a lot of damage on a LS1 if you overheat it!
Change the injectors either at the tuner or just before you go as the mapping will not be correct for that size injector.
Good Luck
