fuel injectors & maf reprograming

Just wondering if there are any problems or would it be inefecient to use larger than needed fuel injectors? .............On the maf can you have them reprogramed how,where,$$$. Also can I tune for larger injectors without pro-m using the stock maf. I have a predator on the way. Any answers or advise on doing a better search would be appreciated, I've been looking but not finding just what I'm looking for in the threads.

If you aren't using any kind of Forced Induction then it will pretty much be a waste of money. The stock 30# injectors can handle any of the bolt ons with ease.

I'm pretty sure he drives a SVT, I've seen him over at Focal Jet. Ask Tom, he's been messing around with a new device that lets you "recalibrate" stock MAF sensors.

I guess I didn't phrase my original question very well, but i'm mainly looking for some basic information about having a maf reprogramed, becouse I could buy a used maf inexpensivly BUT finding one to fit the application and be programed for what i'm looking for is a longshot. For the injectors i guess it's an odd question and maybee why I couldn't find what I was looking for in the threads....What changes would there be in efecency in changing ingectors and tuning for them.....this would be becouse i'm thinking of getting much larger injectors than i could need now to make building on to my meager starting point

I've found my injectors now I went with the 50 lbs for 175 shipped from AEsnaola@chartermi.net so i guess it won't make much difference if a larger injector would be wastefull now
