Anyone have any luck with these for their 4.7? just looking to squeak out a lil better mpg.

 

I know SCT was doing something for the 4.7, but then heard they put it on the back burner to work on the Hemi release.
I believe Air Ram has one, and likes it. Maybe he'll chime in here as I noticed he's been back on here recently...

 

had a jet performace chip... hated it, took it off and the truck runs better. i wanna kno what this airram guy has!

 

yeah just pulled up his info and threads, its a 2002 4.7, ive noticed online it looks like it only goes to 03 and then they just stopped with the 4.7, think thats cause the darn hemi came out lol.

 

WhiteRam did you have the stage 1 or stage 2 jet chip? I've got the stage 2 and my truck runs much better than it did before.

 

i had stage 1...is stage 2 alot better?

 

I have heard stage 1 doesn't do much, but the stage 2 actually works.

 

looks like i might have to invest..

 

I've got the Stage 2 Jet Chip on my truck, and I'll give you my experience with it: For the $200 I spent, I'm fairly happy. I picked mine up from RPMoutlet, which was the cheapest retailer I could find at the time. The stage 2 does demand 91 octane or better, I tried to cheap out and put in 89, but the truck just felt laggy. I did pick up a little but of extra mileage, but not really anymore to justify the extra 20 cents per gallon. I'm saving maybe a buck per tank of gas. Add in the cost of the chip, and I figure it will take about 7,500 miles to break even. So if your looking at for pure fuel economy reasons, don't. However, the throttle response is much better, the truck has a bit more get up and go than it did before, and the shifts (I've got an automatic) are much smoother and crisper. I've had it for about four months and put on about 5,000 miles and haven't experienced any issues with it, or noticed the PCM "relearning" like some others have claimed. All in all, I'm happy with it, the improved throttle response makes it worth to me, but don't expect to save yourself much at the pump.
