RE: MAF INFO NEEDED
I have actually never tried to tune a car with both and EFIE AND a MAF. I usually always just use the EFIE.

I would turn the MAF off, and tune the EFIE. That will give you the best gains. If you still think there's more to be gotten after the EFIE is tuned, then you can try using the MAF enhancer too, but use it at a very low setting.

Now, from what you're saying, I suspect you either have the frequency MAP enhancer mis-installed, or have it set way too aggressively. Somehow you're confusing the computer. That is nearly always bad for gas mileage. So if you use the 2nd device, be sure it's installed correctly, and set it to a very low setting. If it still confuses the computer, don't use it.
