almost done with my 357 le2 build, i have installed the 32lb injectors already. can i start it and do the break in with these injectors? then can i drive it 30 minutes to the shop to get it tuned? i can trailer it there if i have to but woudl like to put soem heat cycles through the trans and rear end.

 

What size injectors in the current tune? If its set up for the stock injectors, the 32's will overfuel it by more than 28%. The long term fuel corrections can only pull out about 15% fuel, and then it relies on the short-terms, which are going to be hit-or-miss in being able to control the fuel. Pouring in all that extra fuel could wash the lubrication off the cylinder walls, and damage the rings.

If you have a stock tune, put the stock injectors back in. Then don't take it anywhere near red line.
