Re: Jet Stage-1 Worth the money.
with the Hemi, intake, cat-back and stage 2, performance is really nice. I am very pleased. I imagine that those mods on the 4.7 would be very similar. As far as mileage - I got a good increase in mileage with the CAI alone. After adding the cat-back, mileage stayed about the same, but with more oopph. The stage 2 chip DID decrease the mileage, compared to intake and exhaust alone, but with the whole package of the three mods, mileage is better than bone stock. Anyway, I didn't get a Hemi 4X4 for fuel mileage..... I got it cause it goes WAAAAAAAAAAHHHHH!!!!!
If you are strictly looking for MPG increase, go with the CAI only.
