Re: Jet Stage-1 Worth the money.

I have a hemi so it may be different but I bought a stage one and got a bit of performance but no mileage and possibly less mileage. too early to tell but I know it isn't getting better. I put the AEM CAI on after and that helped in every direction except my foot got a bit heavier for a while. Has a nice sound and moves when the rpm's get up. Mileage up a bit

Re: Jet Stage-1 Worth the money.

Also watching this one. Just installed the K&N CAI since its the only one available for the 4.7, and did notice a power increase. Might go with the Stage 2 since folks here haven't noticed much change with the Stage 1 chip.

Re: Jet Stage-1 Worth the money.

I got the stage 1 for the extra mileage but I haven't seen it. I am giving it a couple more weeks and if nothing else changes I may just take it off.

Re: Jet Stage-1 Worth the money.

I'm also curious what peolpe have to say about the stage 1 chip, I did however read on the Jet website that it requires the use of 89 octane fuel, that doesn't help if your trying to lower fuel cost.

Re: Jet Stage-1 Worth the money.

I've seen a couple of threads of people promising performance reports after installing the Jetship 1 & 2. But once they install it, it is like the Bermuda Triangle... they vanish :-)

That is why I am holding back on this mod. If I were to pay 300.00 for a mod, I want to see real results. I know at least 2 other XK owners that put this mod on hold because of the same.

I was interested in the Stage I on a V6. But nobody has reported results as of yet...

Re: Jet Stage-1 Worth the money.

Well I had the stage 1 chip in a few weeks and didn't notice any mileage increase. I just pulled it out and will go a couple weeks without and see if the numbers are the same. Not scientific. I did not notice any mileage after puting it in, and now I will recheck without it to make sure nothing else changed. I had also put the AEM CAI on right after the chip. SO this will be the real test. The CAI did a lot more to improve performance than the chip did. I still have the stock exhaust. Makes enough noise for me and the CAI upped that to a nice growl. Th eonly problem is summer blend gas is startin gto show and that will increase mileage in its own right.

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.

Re: Jet Stage-1 Worth the money.

Thanks Hemi. What I am seeing supports what you say. I love the performance of this vehicle and thought if I could get even better performance and some mileage great. The chip helped a bit on the performance but doesn't seem to on mileage. The cai is just all around great. Ok not for water fording but something has to give. I love my Jeep!

I was in Canada on the weekend and they now have a special $4,000 gas guzzler tax on this. You have to like that socialist spirit. We''ll tax what you want out of your reach so you'll buy what we want you to have. Lenin would be so proud. Probably has something to do with that Kyoto treaty they signed.
