I bought an '07 Silverado 5.3 4x4 last month. It came with a couple mechanical/electrical upgrades that I'm looking at getting rid of. I have the same engine in my '99 but get MUCH worse gas mileage in the '07. Now I'm not a mechanical guru whatsoever... I'll have to post some pictures, but off the top of my head there is a K&N Fuel Injector Kit that reads "Stage 2" on it. I'm guessing part of that kit includes an air filter since the factory housing for the air filter is gone. There is power running from the battery to the K&N system in 2 places. Does that mean blower? I'm also pretty sure the computer has been reprogrammed. That truck has some get up 'n go. I'm not a flashy guy, I'd rather have factory basics.
My questions are:
Should I keep the K&N system?
Is it in my best interest to reprogram to factory defaults?
I know pictures would help out a lot... I'll try to get some up sometime soon. Thanks in advance for some advice!
