stock is 80mm...so i went with the modernmuscle 87 mm. It was nice...but the work just wasnt top notch....so i sent it to fastman to cleanup. MM claims it ads 12 hp...dyno proven.

If your gonna do it just from personal experience, get fastman to port it all the way thru whatever size your gonna get. Had a 85mm on my 08 that was just ported at the ends and there was very minimal difference, sold that and bought one that the butterfly was swapped out and ported 85mm all the way thru and it really opened up the top end and throttle response. Have heard it can cause idle issues on some Jeeps though but mine never had any issues

Scott, was there a difference before and after you sent it for the extra work?
Mine just arrived.

Much better with the 87mm ported, HPE CAI and a tune. Really gets up and goes now.

good to hear! I got my first 4.0 0-60 this morning! These 13's really roar once you get 3000 miles and with a few little mods! RG told me the 13's were faster due to a few changes with track mode(70/30 split vs. 12's 60-40) tuning and tb's....HE WAS RIGHT!

That's quick!
