Do you REALLY need to reprogram for 32# injectors?

I'm planning out the "refresh" of my car and there is a chance I'll have a few weeks/months between getting some hard parts on the car and a dyno tune from Bryan Herter. The only thing that might NEED a reprogram would be the injectors, how many have run 32# injectors without a PCM reprogram? Aside from the performance difference, do I run the risk of fouling plugs, screwing up a catalytic converter, etc?

This is not a daily driver, I can keep it off the road until a dyno tune... I just won't want to.

The fuel trims can correct for like 15-20%. You're talking like 28%.
You don't need to do anything if it's worth the risk of nuking the cat and washing oil off the cylinder walls. lol

So my sarcasm meter just registered a hit but Orem is scary close to Provo where I believe sarcasm is punishable by death... So I'm really not sure what to do.

Thanks for the reply dude! The more I think about it the more I will likely just collect parts and get everything done all in one shot.

Your sarcasm meter should have been pegged.

Thanks Shoebox.

By the way, if it were legal to marry a website here in NJ I would have married yours last week. Awesome stuff and THANK YOU for documenting and posting all of that. I hope you know how useful that site is, especially in 2010 when most of the favorites I saved years ago are now dead.

It would be 32-24/24 = ~33% rich!
