I have the factory injectors. Is there a bigger size i can get without having to get the computer reprogrammed?

 

no matter what injectors you put in you should program for them.

 

what he said

 

I have gone to 30#/hr with the stock PCM flash (Hypertech). It ran OK. When I went to 36#/hr, the car runs rich due to a PCM cal of 24 in the flash. Very difficult to start. I purchased LT1-edit. Now running 72#/hr Low-Impedence Siemans with an Acceleronics driver box. (1997 - 383/D1)

 

go ahead and run 30s on stock programing, wash the oil off the cylender walls and take the rings out from to much fuel. running rich is just as bad as running lean.

 

Dynoing tuning of a blown car is cheap insurance to keep the engine healthy. I would get a set of 42 # injectors and have the car tuned.
