Hybrid MPG After Preload/Spacer Kit, New Wheels & 33" Tires

Two weeks back, I added a Stillen intake to my car, and I can't lie, I didn't have the best of experiences. The check engine light kept turning on with lots of error codes, such as the ones shared in the pictures below. I had to check each link twice, making sure all was set up right, but no luck. Don't think I'd advise anyone to get this intake if you're thinking about getting one. Not to be rude, but it was a lot of trouble. On the bright side, though, a few days after putting it in and I noticed the troubles, I called Stillen's help team. I must say, they were super kind and fast to answer. They said sorry for the trouble and wanted to fix it by giving me their Offroad cat-back exhaust in its place. They will send it next week, so I hope it fixes stuff and makes up for my troubles. .

Posting this up in case anyone was curious...

I added some Lock Off Road Combat wheels (17"), 33x12.5 Arroyo RTs, and a Peak front/rear trail kit with UCAs.

If I'm easy on the throttle, I've been able to average around 19 mpg with all the combined driving I do over 3 gas tanks. Definitely took a little hit, but I was sitting around 20 before. The lower numbers could be due to colder time of year and winter blend gas, so it may be higher depending on gas/weather.

The real test will come when we start to add bigger tires, camper, and more weight with armor. But so far so good.
