I'm going to instal my new 42lb injectors,but my MAF is calibrated for my old 36lb injectors. I dont have the money to calibrate it again YET. Any suggestions to keep it close to tuned until I fork over the cash.

What kind of chip do you have? If its an autologic chip, you can have it reprogramed for the 42's for about $50ish

I have no idea,Byron did it if that helps! I,m gonna race tonight,so is it going to affect me in a bad way or to compinsate for bigger injectors I can drop the fuel press down a couple pounds?

Ask byron to reburn it for 42 lbs injectors and a 36lbs MAF. I can't think right now, but I think you need to INCREASE fuel pressure, not decrease it when using a smaller MAF with larger injectors. Personally, I wouldn't race it with the mis-match if its a high HP boosted car.
