Just installed my JLT intake and SCT tuner last night. All I can saw is wow the truck isn't the same. A lot more power. I decided to go with JLT intake because it needs a tune for it to run so I figured it'd add some juice. Also it isn't cali legal so jlt must be doing something right haha. JLT has a YouTube video showing them getting 360-370 rwhp with just there intake and custom tune. Currently had it on a half a day. Mpg in town is noticeably higher went from 11.2-12.4. To right now the truck reading 14.7. So, so far so good. I would seriously recommend this.
