Do I need to have my tune changed if I put a set of 32 lb injectors on my car?

I don't ask because I'm trying to pick up HP, I am just thinking about replacing them in pursuance of a mileage problem.

The racetronix 32 lb's seem to be the best deal, especially since they cost less than autozone quoted me for stock replacements.

Any advice is appreciated.

 

You have to reprogram your PCM w/the new injectors. The 32 lb. injectors will make your car run richer than the stock injectors, with the factory tune.
