Not true, you will likely lose mpg's with LT's. I lost 1-2.

Man, if I lose with headers AND a cam (when that time comes), I would be down to single digits on E85. I would be filling up every week

That sounds like a tuning issue rather than a hardware issue

With all my mods my highway fuel economy is the same as stock, no better and no worse. City is a different story. City its less then half of stock.
